Friction is the correct answer.
Answer:
<em>Increase in wave frequency only</em>
Answer:
4.00m
Explanation:
at that instant where it is dropped all the mechanical energy is gpe which is 71.9
and the formula for gpe = mass (1.80) * height * gravitational field strength (i'm using 10 m/s2)
height of football stadium
= 71.9/[(1.80)(10)]
= 71.9/18.0
= 3.99444..
= 4.00 (3 sf)
Answer:
<h2>1.67 m/s²</h2>
Explanation:
The car’s acceleration can be found by using the formula

where
v is the final velocity
u is the initial velocity
t is the time taken
a is the acceleration
From the question we have

We have the final answer as
<h3>1.67 m/s²</h3>
Hope this helps you
