To solve the problem, use Kepler's 3rd law :
T² = 4π²r³ / GM
Solved for r :
r = [GMT² / 4π²]⅓
but first covert 6.00 years to seconds :
6.00years = 6.00years(365days/year)(24.0hours/day)(6...
= 1.89 x 10^8s
The radius of the orbit then is :
r = [(6.67 x 10^-11N∙m²/kg²)(1.99 x 10^30kg)(1.89 x 10^8s)² / 4π²]⅓
= 6.23 x 10^11m
It bends light rays inwards because it is a converging lense
Answer:
Time, t = 10 seconds
Explanation:
Given the following data;
Mass = 10kg
Force = 10N
Final velocity = 10m/s
Initial velocity = 0m/s
To find the time;
First of all, we would find the acceleration of the box.
Force = mass * acceleration
10 = 10 * acceleration
Acceleration = 10/10 = 1m/s²
Now, we can find the time by using the first equation of motion;
V = U + at
10 = 0 + 1t
10 = t
Time, t = 10 seconds
Therefore, it will take 10 seconds for the box to come to a complete stop.
Impermeable is a substance that is water proofed e.g glass, aluminium e.t.c <span />
Answer:
100 ft
16 ft/s
16 ft/s
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity
s = Displacement
a = Acceleration due to gravity = 32 ft/s² (negative upwards and positive downwards)
The function here is of the form which is one of the equations of motion
From another equation of motion
The maximum height the ball will reach is 100 ft
When s = 96 ft
The velocity of the ball when it is 96 ft above the ground on its way up is 16 ft/s
On the way down when it will be 96 ft above the ground it would travel 100-96 = 4 ft from the maximum height
The velocity of the ball on the way down when it is 96 ft above the ground is 16 ft/s
