Answer:
The change in temperature,
Explanation:
Given that,
The temperature in Spearfish, South Dakota, rose from in just 2 minutes. We need to find the temperature change in Celsius degrees. Change in temperature is given by final temperature minus initial temperature such that,
The relation between degrees Celsius and degrees Fahrenheit is given by :
Here, F = 49 degrees
So, the change in temperature is 9.45 degree Celsius. Hence, this is the required solution.
a) The acceleration of the proton is
b) The time required to reach the given velocity is
Explanation:
a)
This is a motion at constant acceleration, so we can use the following suvat equation:
where
v is the final velocity
u is the initial velocity
a is the acceleration
s is the distance covered
For the proton in this problem, we have:
is the final velocity
is the initial velocity (it starts from rest)
is the distance covered
Solving for a, we find the acceleration:
b)
For this part, we can use the following suvat equation instead:
where:
v is the final velocity
u is the initial velocity
a is the acceleration
t is the time taken for the velocity to change from u to v
We have here the following data:
is the final velocity
is the initial velocity (it starts from rest)
Solving for t, we find
