When a body falls freely under gravity, then the work done by the gravity is ___________

iren [92.7K]

Answer: positive

Explanation:

Gravity can be defined as the force with which the body is attracted towards the center of the earth, or towards any other body. If the force acting on the body is in the direction of displacement then the word done by the applicable force is positive. This causes the free fall of the ball under the influence of gravity is also positive.

A light-rail commuter train speeds up at a rate of 1.65 m/s 2 and takes 19.0 s to reach its top speed. How far down the tracks d

Margarita [4]

Answer:

297.8 m

Explanation:

We are given that

Acceleration= $a=1.65m/s^2$

Time,t=19 s

We have to find the distance covered by the train when it reach its top speed if starting from rest.

Initial speed=u=0

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

Using the formula

$s=0(19)+\frac{1}{2}\times 1.65(19)^2$

$s=297.8 m$

Hence, the train covered 297.8 m when the train go to reach its top speed if starting from rest.

Two of the types of infrared light, IR-B and IR-A, are both components of sunlight. Their wavelengths range from 1400 to 3000 nm

Elis [28]

Answer:

The IR-A is the greatest energy per photon compare to that of IR-B.

Explanation:

Given that,

Wavelength of (IR-B)= 1400 nm

Wavelength of (IR-A)= 700 nm

We need to calculate the energy for IR-B
