1000 J

Answers

Answer 1
Answer:

The total amount of work done will be "50 J". To understand the calculation, check below.

Work done and Force

According to the question,

Force, F = 5N

Distance, d = 10 m

We know the formula,

→ Work = Force × Distance

or,

→ W = F × d

By substituting the values, we get

       = 5 × 10

       = 50 N/m or,

       = 50 J

Thus the response above is correct.

Answer 2
Answer:

Answer:

50N/m or 50J

Explanation:

Work is defined as product of force & distance. Hence per the parameters,

Force = 5N and Distance is 10m

Therefore Work =F x d

Work = 5N x 10m

Work =50N/m or 50J

What things affect gravity

Answers

The force of gravity = GMm / r^2, where G is gravitational constant, M is mass of one object, m is mass of another object, r is distance between them.

So, mass of objects affect gravity as well as the distance between the two objects.
Distance and mass affect gravity. If an object has a greater mass, it's gravitational pull will be stronger. And if an object is further away from the one that is exhorting the gravitational pull, then the gravitational pull on the object will be weaker than on closer objects.

If a hockey puck slides on a perfectly frictionless surface, it willeventually slow down because of its inertia.

Answers

If the surface is perfectly frictionless AND level ... no ups and downs ... then the puck never slows down or stops. There's nothing to make it do so. (Notice that "perfectly frictionless" means no air resistance either.)

1.A poorly tuned Yugo can accelerate from rest to a speed of 28 m/s in
20 s.
a) What is the average acceleration of the car?
b) What distance does it travel in this time?

Answers

  1. The average acceleration of the car is 1.4 m / s^2.
  2. The distance travel at this time is 560 m.

Explanation:

Average acceleration is defined as the rate of change of velocity to the rate of change of period. Change of velocity refers to the difference between final velocity and initial velocity. The unit of acceleration is meter/sec/sec (or)   m s^2.

Avg Acceleration=(Final velocity - Initial velocity) /(Final time - Initial time)

a. To find the average acceleration of the car, (initial velocity and initial time   is 0, the final velocity is 28 m/s, final time = 20 s)

               Avg acceleration of the car = (28 - 0) / (20 - 0)

                                                              = 28 / 20 = 1.4 m / s^2.

b. The distance traveled is given by the product of speed and time

     Distance traveled = Speed * Time

      The Distance traveled by the car = 28 * 20 = 560 m.

Final answer:

By applying basic physics formulas, the car's average acceleration can be determined as 1.4 m/s², and the distance it travels in 20 seconds is 280 meters.

Explanation:

To answer this question, you'll need to apply basic physics formulas. Let's go step by step:

a) What is the average acceleration of the car?

Acceleration is defined as the rate of change of velocity per unit of time. The formula is Acceleration = (Final speed - Initial speed) / Time. Here, the initial speed is 0 (because the car is starting from rest), final speed is 28 m/s and time is 20 s.

So, Acceleration = (28 m/s - 0) / 20 s = 1.4 m/s². That's your answer for part a.

b) What distance does it travel in this time?

The distance traveled by the car can be found using the formula of linear motion: Distance = Initial speed x Time + 0.5 x Acceleration x Time². Since the car starts from rest, the initial speed is zero, and this component of the formula will be zero.

So, Distance = 0 + 0.5 x 1.4 m/s² x (20 s)² = 280 m. So, the car travels 280 meters in that time.

Does gravity affect your weight???

Answers

Yes. beacuse the gravity pulls you down. Example:If you are in the space you will weight less, beacuse there's no gravity.
              hope this help. :)
Weight is a force caused by gravity. The weight of an object is the gravitational force between the object and the Earth. The more mass the object has the greater its weight will be.
