what are the aerodynamics of a cow

When you turn the ignition switch to the ENG STOP position after the engine fails to start, you must wait for approximately 15 seconds before attempting to start the engine again.

This waiting period allows the starter motor to cool down and prevents damage to the vehicle's electrical system.

The ENG STOP position cuts off fuel and ignition to the engine, effectively stopping its operation.

By turning the ignition switch to this position, you interrupt the starting process and give the starter motor time to rest.

Waiting for 15 seconds ensures that the starter motor is not overheated and allows it to regain its normal operating temperature.

This prevents potential damage to the motor and the vehicle's electrical system.

Once the 15-second waiting period has passed, you can then turn the ignition switch back to the RUN position and attempt to start the engine again.

If the engine still fails to start, it may be necessary to troubleshoot further or seek assistance from a qualified mechanic.

To get the angle of separation between the legs of a compass used in drafting, we can make use of trigonometry concepts. Let x be the angle of separation between the legs of a compass. Also, note that the legs are each 100 cm long. Then, we have: tan x = (1/2)(15/100)tan x = 0.075x ≈ tan⁻¹ (0.075) ≈ 4.304 degrees

Therefore, the angle of separation between the legs of the compass used in drafting for drawing perfect circles to the nearest degree is 4 degrees.

Geometry is the part of arithmetic worried about unambiguous elements of points and their application to computations. In trigonometry, there are six common functions for angles. Their names and shortened forms are sine (sin), cosine (cos), digression (tan), cotangent (bed), secant (sec), and cosecant (csc).

Answer:

the car’s final displacement is 60 m

Explanation:

Given;

initail velocity of the car, u = 0

acceleration of the car, a = 0.8 m/s²

time of motion, t = 10 s

The first displacement of the car:

\(x_1 = ut + \frac{1}{2} at^2\\\\x_1 = 0 + \frac{1}{2} (0.8)(10)^2\\\\x_1 = 40 \ m\)

The second displacement of the car;

acceleration, a = 0.4 m/s²,   time of motion, t = 10 s

\(x_2 = ut + \frac{1}{2} at^2\\\\x_2 = 0 + \frac{1}{2} (0.4)(10)^2\\\\x_2 = 20 \ m\)

The final displacement of the car;

x = x₁  +  x₂

x = 40 m  +  20 m

x = 60 m

Therefore, the car’s final displacement is 60 m

The transition of an electron in the hydrogen atom that releases the emission of light happens when: there are electrons that quickly drop from the higher orbit to the lower. When those electrons drop, energy will be released in form of light emissions.

When hydrogen atom absorbs energy, their electron will be raised to a higher energy level. This condition is known as an excited state. Because the higher orbit has less stability, those electrons tend to revert to the lower orbital. The drops of the electrons will emit energy in the form of light emissions. Hydrogen atoms have an emission spectrum that is known as the Balmer series.

Potential Energy - (Measured in Joules) - Potential energy is the energy that is stored in an object due to its position relative to some zero position.

Mass - (Measured in Kilograms) - Mass is the amount of matter in a body, regardless of its volume or the forces acting on it.

Acceleration Due to Gravity - (Measured in Meter/Square Second) - Acceleration due to gravity is the acceleration gained by an object due to the gravitational force.

Height - (Measured in Meters) - Height is the distance between the lowest and highest points of a standing person/shape/object.

Data:

m = 140 kg

h = 10 m

g = 9.8 m/s²

Ep = ?

The formula to calculate potential energy:

Ep = m * g * h

We clear, but it is not necessary, since we want to calculate the potential energy.

The reason why it is given in Joules is because N * m, are units of Joules, and N = Kg * m/s^2. It is the ratio of the Joules.

The potential energy of the body of mass m = 140 kilograms and located at height h = 10 meters is equal to 13720 Joules.

The total weight of screws and nails that Henry bought to build the skate board ramp is 13/20 pounds.

To find the total weight of screws and nails, we need to add the weight of the screws and the weight of the nails.

Henry bought 1/4 pound of screws and 2/5 pounds of nails, so

Total weight = 1/4 + 2/5 pounds

Total weight = (1 x 5)/(4 x 5) + (2 x 4)/(5 x 4) pounds

Total weight = (5/20) + (8/20) pounds

Now that both fractions have the same denominator, we can add them together,

When the mother with a mass of 60 kg skates at a velocity of 4 m/s towards her child, who has a mass of 20 kg and is initially at rest, the system has a certain momentum. Assuming negligible friction, the total momentum before and after the interaction remains constant (conservation of momentum).

Initial momentum = Final momentum

Initial momentum = (Mother's mass) x (Mother's velocity) + (Child's mass) x (Child's velocity)
Initial momentum = (60 kg) x (4 m/s) + (20 kg) x (0 m/s) = 240 kg m/s

After picking up the child, the combined mass of the mother and child is 60 kg + 20 kg = 80 kg. Let's denote their new velocity as V.

Final momentum = (Combined mass) x (New velocity)
Final momentum = (80 kg) x (V)

Now equate initial and final momentum:
240 kg m/s = (80 kg) x (V)

Solve for V:
V = 240 kg m/s / 80 kg = 3 m/s

The new velocity of the mother and child together is 3 m/s.

The evidence that some meteorites originated inside large bodies includes the presence of chondrules, which are believed to have formed in the early solar system, and the isotopic composition of certain elements that suggests they underwent a process of differentiation.

Chondrules are small, spherical grains found in some meteorites that are thought to have formed through a rapid heating and cooling process in the early solar system. This suggests that these meteorites originated from a larger body that had undergone some form of thermal processing. The isotopic composition of certain elements found in some meteorites also provides evidence for differentiation. For example, the presence of isotopic anomalies in oxygen, chromium, and other elements suggests that these meteorites underwent a process of melting and differentiation within a larger parent body.Other lines of evidence for internal differentiation within meteorite parent bodies include the presence of layered structures and variations in mineral compositions. These findings suggest that some meteorites are fragments of larger bodies that formed and differentiated in the early solar system.

The bullet will miss the target by a distance of 1.225 m.

The equations of motion can represent the relationship between the velocity (v and u), acceleration, time (t), and displacement (s) of a moving object.

The mathematical form of the equations of motions can be shown as:

\(v= u +at\\S=ut +\frac{1}{2}at^2\\ v^2-u^2=2aS\)

Given, the distance between the hunter and target, d = 140 m

The speed of the fired bullet, v = 280 m/s

The time taken by a bullet, t = d/v = 140/280 = 0.5 sec

Answer:

I. Final velocity, V = 10m/s.

II. Distance, S = 10m.

Explanation:

Given the following data:

Acceleration = 5m/s²

Time = 2 seconds

Since the vehicle starts from rest, initial velocity = 0m/s

To find the final velocity, we would use the first equation of motion.

V = U + at

Substituting into the equation, we have

V = 0 + 5*2

V = 0 + 10

V = 10m/s.

Now, to find the distance covered, we would use the second equation of motion.

S = ut + ½at²

S = 0*2 + ½*5*2²

S = ½*5*4

S = 20/2

S = 10m

3)No, it's speed is constant.

(a) The equilibrium temperature of the system is 0°C.

(b) There is no unmelted ice when the system reaches equilibrium.

The three ice cubes have a total mass of 3 * 111.0 g = 333 g. The water has a mass of 0.840 kg = 840 g. The specific heat capacity of water is 4.184 J/g°C. The latent heat of fusion of water is 333.55 J/g.

When the ice cubes are added to the water, the ice cubes will absorb heat from the water until they reach 0°C. Once the ice cubes reach 0°C, they will begin to melt. The heat required to melt the ice cubes will come from the water.

The water will continue to lose heat until all of the ice cubes have melted. The total heat required to melt the ice cubes is:

Q = m * Lf

Q = 333 g * 333.55 J/g

Q = 111,476 J

The total heat lost by the water is:

Q = m * c * ΔT

Q = 840 g * 4.184 J/g°C * (21.0°C - 0°C)

Q = 75,056 J

Since the heat lost by the water is equal to the heat required to melt the ice cubes, the equilibrium temperature of the system is 0°C. At 0°C, the water will be in equilibrium with the ice. There will be no unmelted ice when the system reaches equilibrium.

If an object moves around a circle, of radius 6 m, with constant velocity, the angular velocity of the object is 1.67 1.67 radians per second.

The angular velocity of an object moving in a circular path can be calculated using the formula:

ω = v / r

Where ω is the angular velocity, v is the constant speed, and r is the radius of the circle.

In this case, we are given the constant speed (v) as 10.0 m/s and the radius (r) as 600 cm. We need to convert the radius to meters in order to use the formula correctly:

r = 600cm * (1m / 100cm) = 6m

Now we can plug in the values and solve for the angular velocity:

ω = v / r

ω = 10.0 m/s / 6 m

ω = 1.67 radians per second

Therefore, the angular velocity of the object is 1.67 radians per second.

Answer:

The diver was most likely wrong because of refraction. Light bends in water, leading to some optical illusions. In the case of the pool, the light bends as it enters the water, making it look shallower than what it really is when looked at from the top. Light rays reflected from the bottom of the pool are refracted at the surface of the water, however our eyes trace the light rays back into the water as though traveled in a straight line, and not refracted at all. This results in an image of the object that appears at a shallower depth to where it really is.
