How far will a body move in 4 seconds if uniformly accelerated from rest at rate of 2m\sm\s​

Physics

Lubov Fominskaja [6]3 years ago

Answer:

16 m

Explanation:

For an object in uniformly accelerated motion (=with constant acceleration), the distance covered by the body can be found by using the following suvat equation:

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

where

s is the distance covered

u is the initial velocity

t is the time

a is the acceleration

For the body in this problem,

u = 0 (it starts from rest)

a=2 m/s^2 is the acceleration

Substituting t = 4 s, we find the distance covered:

s=0+\frac{1}{2}(2)(4)^2=16 m

Which switch configuration creates a short circuit?
lara31 [8.8K]
I think the answer would be Switch 1 open; switches 2, 3, and 4 closed. It is letter D. This will happen when there is a low resistance and a high circuit so from the choices above, when two bulbs are open and one bulb is close, so there is a low resistance and high voltage.

2.More people will be interested in studying science

But science would probably be focused on space exploration and there will probably be less scientists in other fields such as chemistry.

One runner in a relay race has a 1.50 s lead and is running at a constant speed of 3.25 m/s. The runner has 30.0 m to run before
yarga [219]
The second runner must run 3.3m/s. If the leading runner is 1.5 seconds ahead and there are 30m left, the second runner would need to run slightly faster than the lead in order to finish at the same time. To calculate this I did 30/1.5 which gave me 0.05. I added this onto the speed of the lead runner to get 3.3m/s :)

A mole of red photons of wavelength 725 nm has ________ kj of energy.
yuradex [85]
According to the general rules and basic knowledge of physics, without any doubds I can say that a mole of red photons of wavelength 725 nm has  [D] 165 kj of energy. I converted <span> a wavelength into energy in that way : 
</span>(E)= 6.023 x 10 ^23 x 6.625 x 10 ^ -34 x3 x 10^8/725x10^-9==0.1651 x10 ^ 6 J = 165 Kj.<span>
