Answer:

5000 W

Explanation:

Applying,

P = W/t................. Equation 1

Where P = Power, W = work done by the car, t = time.

But,

W = F×d ............. Equation 2

Where F = Force, d = distance

Substitute equation 2 into equation 1

P = (F×d)/t.............. Equation 3

From the question,

Given: F = 2000 N, d = 50 m, t = 20 seconds.

Substitute these values into equation 3

P = (2000×50)/20

P = 5000 W

Answer:

7. (C) 12 m/s

8. (D) 44.1 m

9. (C) 9.8 m/s^2

Explanation:

8. y = -(1/2)gt^2

= -(1/2)(9.8 m/s^2)(3 s)^2

= -44.1 m

This means the ball traveled 44.1 vertically downwards.

Answer :light

Explanation:  

A television set is another device that operates by the transformation of energy. An electrical beam from the back of the television tube strikes a thin layer of chemicals on the television screen, causing them to glow. In this case, electrical energy is converted into light.

Explanation:

apparent apparent weight is how hard astronaut pushes against it which is the normal force

n m a y + mgm open parenthesis y + and close parenthesis and = m open parenthesis a y + and so i need the acceleration of the astronaut since initial velocity is 0 and yby over l 45 m per second over 15 x 30.0 m m per second squared

Explanation:

Start with what you know and list your knowns and unknowns

F = ma

F= 3N

m = 6kg

a =?

3N = 6kg x a

solve for a

3N / 6kg = a

Answer:

Explanation:

Gravity pulls everything down at the same rate of 9.8 m/s/s. If you're looking for the normal force, which is the same as the weight of the object, we'll find that, just in case.

w = mg which says that the normal force/weight of an object is equal to its mass times the pull of gravity:

w = 4.0(9.8) so

w = 39N

Work is transfer of energy in an object when it travel some distance by external force,

Work= force × displacement

Explanation:

Use Ohm's Law

V / R = I

I = 5A

V = 110V

R =?

Solve for R

Answer:

When object falls freely we can say

its initial speed will be ZERO

and its acceleration due to gravity must be

a = g = 9.8 m/s^2a=g=9.8m/s2

Now we need to find the distance of free fall in 3 s of time

So here we will use kinematics

y = v* t + \frac{1}{2} at^2y=v∗t+21at2

now we will plug in all values in it

y = 0 + \frac{1}{2}* 9.8 * 3^2y=0+21∗9.8∗32

y = 44.1 my=44.1m

So it will fall by total distance of 44.1 m

Explanation:

When something is moving, we call it is in motion. It can be also defined as a change of position in relation to another object.

When an object is not moving at all, we call that it was at rest.

To be in motion, there must be a change in position.

Hence, the correct options are "a change of position in relation to another object" and "something is moving".

Answer:

let Tension in the left chain is F

here, Fnet = 0

⇒F - 500N + 250 N - 125 N = 0

⇒F - 375 N = 0

⇒F = 375 N

let r from the left end of the board is the person sitting.

now torque at left end, τ = 0.

⇒375 × (0) - 500N × (r) + 250N × (4m) - 125 N × (2m) = 0

⇒0 - 500r + 1000 - 250 = 0

⇒750 = 500r

⇒r = 750/500 = 1.5 m

Answer:

Let N0 be the initial atoms of Be11

N0 / 2^1 = N0 / 2  Number of Be11 after 1 half-life

N0 / 2^2 = N0/ 4   Number of Be11 after 2 half-lives

30/13.81 = 2.17 half lives

N0 / 2^2.17 = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain

The percentage of the initial sample that will remain after 30.0 s is 22.2 % of atoms remain.

A half of existence is the duration required for something to reduce in size by half. The phrase is most frequently used in reference to radioactive decay, which takes place as unstable atomic particles weaken. There are 29 known factors that can operate in this way.

Every chemical has a unique half-life. Since carbon-10, for instance, has a half-life of only 19 seconds, it is impossible for this isotope to be found in nature.

Let No of the initial atoms of Beryllium-11

No / 2¹ = N0 / 2  Number of Be11 after 1 half-life

No / 2² = N0/ 4   Number of Be11 after 2 half-lives

30 / 13.81 = 2.17 half lives

No / 2²·¹⁷ = N0 / 4.51 = .222 N0 or 22.2 % of atoms remain

Therefore, the percentage of the initial sample will remain after 30.0 s is 22.2 %.

Answer:

v = 34.128 km/hr

Explanation:

Given that,

The initial speed of a truck, u = 0

Acceleration of the truck, a = 0.3 m/s²

Distance moved, d = 150 m

Let the final speed of the truck is v. Using third equation of motion i.e.

[tex]v^2-u^2=2ad\\\\v=\sqrt{u^2+2ad}[/tex]

Put all the values,

[tex]v=\sqrt{0^2+2\times 0.3\times 150}\\\\v=9.48\ m/s[/tex]

or

v = 34.128 km/h

So, the final speed of the truck is equal to 34.128 km/h.

Answer:

271 K

Explanation:

Answer:

The temperature of Nitrogen is 270.85 K.

Explanation:

A gas that follows Boyle's law , Charle's law and law of pressure , is called perfect gas.

Given data;

[tex]P =101.3 KPa , V = 0.08 m^{3} , \\ n = 3.6 mol , R = 8.31\\T = ?[/tex]

By the formula,

P.V = n .R.T

On putting values

[tex]1.013[/tex] x [tex]10^{5}[/tex] x [tex]0.08[/tex] = [tex]3.6[/tex] x [tex]8.31[/tex] x [tex]T[/tex]

Answer:

a) "gravitation" is the force causing you to go down a waterslide

b) It is "fluid friction" as a solid object (our body) moves over a fluid (the water)

c) It would become "sliding friction" since two solid surfaces slide over each other

d) fluid friction being the weakest friction, switching to sliding friction means a higher decrease in speed and therefore removing the water from a slide will decrease our speed

Answer:

The system will tend to person A

Explanation:

A force is defined as either a pull or a push, in this scenario person A weighs lass that person B, so the resultant effect of the 10N interactive force will tend towards person A.

This is solely because person A is less than person B in weigh
