Explanation:
The satellite exerts a force of 1900 N on the Earth
Explanation:
To answer this question, let's remind Newton's third law:
"When an object A exerts a force (called action) on an object B, then object B exerts an equal and opposite force (called reaction) on object A"
In this problem, we can identify:
The Earth as object A
The satellite as object B
This means that if we apply the law, the force that the Earth exerts on the satellite must be equal (in magnitude) and opposite (in direction) to the force the satellite exerts on the Earth.
Since the Earth exerts a force of 1900 N on the satellite, this means that the satellite also exerts a force of 1900 N on the Earth.

Answer:
Ω
Explanation:
Given that
d(min,0)= 4 cm
d(min,1)= 14 cm
Voltage standingwave ratio = 1.5
Zo = 50 Ω
We know that
d(min,1) - d(min,0) = λ/2
Now by putting the values
14 - 4 = λ/2
λ = 20 cm
We also know that
β=2π/λ
β=2π/0.2 = 10π rad/m
So we can say that
θr= 2β d(min,n) - (2 n + 1)π rad
θr=2×10π ×0.04 −π = -0.2 π rad
We know that
π rad = 180 °
θr= = -0.2 π rad= -36 °
We know that
Here S= 1.5
by putting the values
Ω
In a forward bias, the p-type is connected to the positive side of the terminal and the n-type is connected to the negative terminal of the voltage source. The electrons in the n-type junction travels towards the holes in the p-type junction
In a reverse bias, the junctions are connected to the opposite terminals compared to the forward bias. The free electrons build up on the center creating a neutral layer that widens as voltage is increased.
Answer:
The cart would speed up.
Explanation:
According to Newton's 1st law, object subjected to no force, or net force 0, would have a constant speed. In our case the cart is initially at constant speed, meaning the man exerts a force that is equal to friction force. If he increases the force on the cart, the net force would no longer be 0. The cart would gain an acceleration and increases its speed.
