Answer:
Explanation:
From the equation of Newton's laws of motion
v = u + at where v is final velocity , u is initial velocity and t is time.
150 = 0 + a x 3
a = 50 m / s ²
s = ut + 1/2 at² ; s is distance travelled
s = 50 x 3 + .5 x 50 x 3²
= 150 + 225
= 375 m .
Answer:
the ratio is
Explanation:
Given
The RMS velocity of molecules in a gas is given by
where T=temperature
For T = 387K
For T = 774
dividing eqn 1 and eqn 2
Thus,the ratio is
The answer is 560 because 7 times 80 is 560. Please mark me as the brainliest.
The correct answer would be C because declining a break from exercise is considered overload.

Explanation:
The period of a simple pendulum is given by:
where
L is the length of the pendulum
g is the acceleration due to gravity
In this problem, we have
Substituting into the equation, we find the period:
