Answer:
43.88 meters per second
Explanation:
The computation of the speed is shown below:
As we know that
where,
Distance is 395,000 meters
Time is 9,000 seconds
Now placing these values to the formula
So, the speed is
= 43.88 meters per second
As speed shows the relation between the distance and time and the same is to be considered i.e by applying the formula
Answer:
18.1 V
Explanation:
The electric field between two parallel plates is given by the equation:
where
is the charge surface density
is the vacuum permittivity
For the plates in this problem,
So, the magnitude of the electric field is
Now we can find the potential difference between the plates, which is given by
where
d = 8.0 cm = 0.08 m is the separation between the plates
Substituting,
Answer:
Explanation:
Given
Inclination
Distance of landing point
Considering athlete to be an Projectile
range of projectile is given by
where u=launch velocity
(b)If u is increased by 8% then
new velocity is
Answer:
The angle of refraction is 41.68°.
Explanation:
The refractive index for water is , and for air
: the angle of light with the normal is
; therefore Snell's law gives
