Just after a motorcycle rides off the end of a ramp and launches into the air, its engine is turning counterclockwise at 8325 rev/min. The motorcycle rider forgets to throttle back, so the engine's angular speed increases to 12125 rev/min. As a result, the rest of the motorcycle (including the rider) begins to rotate clockwise about the engine at 4.2 rev/min. Calculate the ratio IE/IM of the moment of inertia of the engine to the moment of inertia of the rest of the motorcycle (and the rider). Ignore torques due to gravity and air resistance.

Answers

The correct answer to the question above is 20 millibar pressure difference between two near locations. The highest surface winds speed occur when there is a 2- millibar pressure difference between two nearby locations. Wind speed or also called as wind velocity is caused by the higher air pressure going to low.

At a given location in space, the magnetic field in an electromagnetic wave is increasing. How is the electric field changing at that same location? a. The electric field is increasing.
b. The electric field is decreasing.
c. The electric field is not changing.

Answers

Answer:

Option a) is correct

Explanation:

In the given question option a) ( i.e the electric field is increasing ) is correct.

The above option is correct because the electric field and the electromagnetic wave both are in the same phase of the EM wave. Thus, the electromagnetic wave and the electric field are directly proportional to each other.

Final answer:

In an electromagnetic wave, the electric and magnetic fields are linked, oscillating in phase. Therefore, when the magnetic field is increasing, the electric field is also increasing.

Explanation:

In an electromagnetic wave, the electric field and the magnetic field are perpendicular to each other and they oscillate in phase. This means when the magnetic field is increasing, the electric field is also increasing, and vice versa. So, the correct answer is option a. The electric field is increasing. It's important to keep this correlation in mind while studying electromagnetic waves, as these oscillations and their interplay are fundamental to how these waves propagate through space.

If we assume that 60 % of the kinetic energy delivered by a 1.80-kg hammer with a speed of 7.80 m/s is transformed into heat that flows into the nail and does not flow out, what is the temperature increase of an 8.00-g aluminum nail after it is struck ten times?

Answers

Answer:

45.6°C

Explanation:

Kinetic energy = $(1)/(2)mv^2$

Use m= 1.80kg and v=7.80m/s (mass and speed of hammer).

K = 0,5*1.80kg*(7.80m/s)^2 = K=54.8J

Heat is 60% of Kinetic energy. Q = 0.6*54.8J = 32.9J

As it is stuck 10 times the total heat is 10*32.9J = Total Heat = 329J

Use the equation $Q = mC_v \Delta T$ to find change of temperature:

$\Delta T = (Q)/(mC_v)$

Q = 329J; m = 8.00g of aluminium; C_v = 0.900J/g°C (For aluminium)

$\Delta T = (329J)/(8.00g*0.900J/g°C)$

Calculating gives Change of Temperature = 45.6°C

What is true about the inertia of two cars, Car A of mass 1,500 kilograms and Car B of mass 2,000 kilograms

Answers

Answer:

Car B

Explanation:

Inertia of a body is the property to oppose its state of rest or state of uniform motion. It is also equivalent to the measure of its mass. Newton's first law of motion is also called as law of inertia.

According to given question, we have to write the name of car having more inertia. So, the body having more mass will have more inertia.

The mass of car A is 1500 kg while the mass of car b is 2000 kg. Hence, car B will have more inertia.

Car B has more inertia then Car A

Advantages of using low energy appliances

Answers

Using low energy appliances can save you a lot of money. The more energy you use the more expensive it can get. Also it is better for the environment if you use the least energy possible. We don't want to be wasting so use less energy. More energy used, more harm it can do on the environment.
