Answer:
s = 45 m
Explanation:
The velocity given in the question is uniform. Hence, the formula for the uniform velocity shall be used here. The formula is given as follows:
where,
s = distance traveled away from the brother = ?
v = constant speed = 3 m/s
t = time taken = (0.25 min)(60 s/1 min) = 15 s
Therefore, using these values in the formula we get:
<u>s = 45 m</u>
The answer to the question which method is not used to improve the tropical forest is letter "A" which is "increased logging". This method worsens the situation, cutting of increases results to the different type of catastrophes like floods, soil erosion, and others.
Answer:
0.99 s
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:
Answer
given,
expression of Kinetic energy of rotating body
ω = 34.0 rad/s
Assuming mass of the particle equal to 13 Kg
and perpendicular distance from the particle to the axis is r = 1.25 m
now,
moment of inertia of particle = ?
from the given expression
..............(1)
we know
v = r ω
putting value in equation (1)
I = 20.3125 kg.m²
Answer:
28 m/s
Explanation:
vf^2=vi^2+2a(delta y)
=sqrt(2* -9.8 m/s^2* -40 m)
=28 m/s
