Answer:

The dilation of time is a phenomenon that results from the theory of relativity proposed on 1905 by Einstein.

This theory, states (under the condition of the invariance of the speed of light in vacuum) the measurement on a body is made with reference to the system in which it is being measured and that time passes at different rates in regions of different gravitational potential.

That is:

<h2>The greater the local distortion of space-time due to gravity, the slower the time passes. </h2>

Consider a situation where a constant force of 25 N acts on an object having a mass of 2 kg for 3 seconds. What is the work done

blagie [28]

Answer:

Work done W =1406.25 J

Explanation:

Work done on a body can be calculated using newton's 2nd laws:

F=ma

$\Rightarrow a=\frac{F}{m}$

Hence acceleration of the block is given by:

$\Rightarrow a=\frac{25}{2}=12.5m/s^2$

Displacement of the object is given by:

$\Rightarrow S=ut+\frac{1}{2}at^2$

Substitute the values

$\Rightarrow S=0*3+\frac{1}{2}(12.5)3^2$

$\Rightarrow S=56.25 m$

Now work done is given by:

W=F.S

W = 25×56.25

W =1406.25 J

Select the statement that best describes gravity.

pav-90 [236]

Explanation:

Gravity is the force of attraction between two objects. It depends upon the mass of the objects and the distance between the objects. Mathematically, the force of gravity is given by :

$F=G\dfrac{m_1m_2}{d^2}$

Where

G is the universal gravitational constant

$m_1\ and\ m_2$ are masses

d is the distance between two masses

So, statement (2) describes gravity "Gravity is the force of attraction between two objects; it is dependent upon the mass of the objects and the distance between the objects".
