Answer:
is the fastest moving type of radiationhe
Answer:
a) a = 2.35 m/s^2
Explanation:
(a) In order to calculate the magnitude of the acceleration of the ball, you use the following formula, for the position of the ball:
(1)
x: position of the ball after t seconds = 87 m
t: time = 8.6 s
a: acceleration of the ball = ?
vo: initial velocity of the ball = 0 m/s
You solve the equation (1) for a:

You replace the values of the parameters in the previous equation:

The acceleration of the ball is 2.35 m/s^2
I would say the atmosphere.
Hope this helps!
D. A river flowing into the sea
The freezing of glaciers would do nothing to the salinity. Hot weather on the other hand, and evaporation, would leave behind the salt and thus it Increases the amount of salt to water in the ocean.
To solve this problem it is necessary to apply the concepts related to Sound Intensity. The unit most used in the logarithmic scale is the decibel and mathematically this is expressed as

Where,
= Sound intensity level in decibels
I = Acoustic intensity on the linear scale
Hearing threshold
According to the values, the total intensity is 32 times the linear intensity and the value in decibels is 83dB
So:




Therefore the sound intensity due to one person is 67.948dB
