Answer:
106417026.88435 m
Explanation:
T = Time period of the satellite = 4 days
m = Mass of the Earth = 5.972 × 10²⁴ kg
G = Gravitational constant = 6.67 × 10⁻¹¹ m³/kgs²
Time period is given by
The radius of the satellite's orbit is 106417026.88435 m
The calculated time is 6 seconds.
Time is defined by physicists as the flow of events from the past through the present and into the future. In essence, a system is timeless if it is unchanging. When describing events that take place in three-dimensional space, time can be thought of as the fourth dimension of reality. Even if time isn't directly connected to energy, it is undoubtedly connected to many other components of energy. For instance, the movement of energy across the universe can affect the direction of time (from the past to the future).
V= 2 m/s
d=12 m
t=?
we know that velocity=displacement / time
time= displacement / velocity
= 12/2
=6 seconds
the calculated time is 6 seconds.

Explanation:
distance covered in the first part of journey : 120×14 = 1680km
distance covered in second part of journey :
90×10 = 900 km
total distance traveled : 1680+900 = 2580km.
total time taken to complete the journey : 14+10= 24 hrs.
therefore, the average speed of the journey = 2580km/24hr = 107.5 km/h.
hope this helps you.
Answer:
b) 2.2 kg
Explanation:
Net force acting on an object is the sum of the two forces acting on the body.
The net force is calculated using the parallelogram law of vectors.
F =
Here A = 20 N , B = 35 N and θ =80°
Net Force = F = 43.22 N
Acceleration = a = 20 m/s/s
Since F = ma, m = F/a = 43.22 / 20 = 2.161 kg = 2.2 kg
