ΑΣ Sign A. keeping everything grounded on Earth. C. planes not being able to fly into space. B. making tall skyscrapers safe, D.

showing us the stars on a dark night. 2. The Earth's gravity is very important to our lives, but so is the gravity of the sun and the moon. The moon's gravity pulls on the ocean and makes the tides rise and fall . The sun's gravity pulls on the Earth and makes sure our planet doesn't go flying out into space. The sun's gravity keeps all the planets spinning around it, and the Earth's gravity keeps the moon close by. Which of the following best describes how the moon and Earth affect one another? A. The moon's gravity keeps Earth in place, B. The moon's gravity keeps the Earth close and the Earth's gravity affects the tides on by, and the Earth's gravity changes the the moon. moon's orbit. C. The moon's gravity creates tides on Earth, D. The moon's gravity creates earthquakes, and the Earth's gravity keeps the moon in and the Earth's gravity creates place. moonquakes.

At a given instant in time, two cars are traveling at different velocities, one twice as large as the other. Based on this infor
Sati [7]

Answer: No, is not possible.

Explanation:

We have two cars traveling at different velocities, one with velocity v and other with velocity 2*v

We want to know of it is possible to say which of these two cars has the larger acceleration at this instant of time.

Acceleration is the rate of change of the velocity, for example, if acceleration = 0, the velocity does not change.

Notice that knowing only the velocity at a given instant of time, we do not have any way of knowing the acceleration of each car.

Such that acceleration is given by the second Newton's equation:

F = m*a

force equals mass times acceleration.

We do not know any of these quantities for the cars, so we can not say anything about the accelerations.

We also could know the average acceleration if we know the change in velocity over an interval of time, such that:

Av acceleration = (change in velocity)/(interval of time)

But here we do not have a change in velocity, so again, we can't say anything about the acceleration.

a generator uses loops of area 0.239 m^2, rotating 373 rad/s in a 0.0639 t magnetic field. how many loops must the coil have to
Kaylis [27]

The loops must the coil have to generate a maximum emf of 2500 will be 439.

<h3 /><h3>What is the faraday law of electromagnetic induction?</h3>

According to  Faraday's law of electromagnetic induction, the rate of change of magnetic flux linked with the coil is responsible for generating emf in the coil resulting in the flow of amount of current.

Given data;

Area,A = 0.239 m²

Angular velocity,ω=373 rad/sec

Magnetic field,B=0.0639 T

Maximum emf,E= 2500V

The formula for the maximum induced voltage is;

E{max} = N ×  B × A × ω

2500 = N × 0.639 × 0.0239 × 373

N = 438.66

N = 439 \ turns

Hence, loops must the coil have to generate a maximum emf of 2500  will be 439.

To learn more about the faraday law of electromagnetic induction refer to;

True or false if an object has energy it must be moving
Drupady [299]

Answer:

Explanation:

If an object is moving, it is said to have kinetic energy (KE). Potential energy (PE) is energy that is "stored" because of the position and/or arrangement of the object. The classic example of potential energy is to pick up a brick. When it's on the ground, the brick had a certain amount of energy.

The hindenburg zeppelin contained 200,000 m^3 of hydrogen, with a density of 0.0899 kg/m^3. What is the mass of the hydrogen?
oksian1 [2.3K]

d=m/v

0.0899=m/200000

or,0.0899*200000=m

m=17980
