<span>Before we can use parallax to measure the distance to a nearby star, we first need to know the Earth-Sun distance.
Not before we find out what the distance between our planet and the Sun is can we use the parallax to measure the distance to a nearby star.

Answer:
Time for the first plane to cover 1 degree of latitude is 0.2hour
Time for the second plane to cover 1 degree of latitude is 0.203hour

Answer:
When you hit a baseball with a bat, you are applying a force only in the time while the bat is in contact with the ball, after that, the horizontal speed of the ball is constant. (if you ignore the friction of the air)
This happens because of the second Newton's law:
Force is equal to mass times the acceleration or:
F = m*a
If we do not have a force, then we do not have acceleration.
This means that the change in position for a fixed amount of time is constant, so horizontal speed is constant.
Chicken is the resistance of the lamp
To calculate the kinetic coefficient of friction is closest to: 1. 0.23.
<u>Given the following data:</u>
- Horizontal force = 4.5 Newton
To calculate the kinetic coefficient of friction:
Mathematically, the kinetic force is given by this formula;

<u>Where;</u>
represents the kinetic force.
is the normal force.
- μ represents the kinetic coefficient of friction.
Making μ the subject of formula, we have:

Substituting the given parameters into the formula, we have;

u = 0.225 ≈ 0.23
