I believe the answer is valcanos because they release sulfur in to the air and other chemicals so it willl affect the anispher
Answer:
<h2>62.5 m/s</h2>
Explanation:
The speed of the car can be found by using the formula

d is the distance
t is the time
From the question we have

We have the final answer as
<h3>62.5 m/s</h3>
Hope this helps you
Answer:

Explanation:
This is a uniformly accelerated motion, so we can determine the deceleration of the car by using a suvat equation:

where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the car in this problem,
u = 27.8 m/s
v = 0
s = 17 m
Solving for a, we find the acceleration:

Answer:
y = 4 Sin (2πt)
Explanation:
Amplitude, A = 4
frequency, f = 1
Wave function is given by
y = A sinωt
where, ω is angular frequency
ω = 2 π f = 2 π x 1 = 2π
So, the desired wave function
y = 4 Sin (2πt)
