~Hello there!
Your question: Which of two factors influence the weight of an object due to gravitational pull?
Your answer: The mass and the radius of the planet are the two factors that influence the weight of an object due to the gravitational pull
The answer is option A.
Any queries ^?
Happy Studying!
Answer:
The value is 
Explanation:
From the question we are told that
The diameter of the storm is 
The wind speed is 
Generally the radius is mathematically represented as
=> 
=> 
Generally the angular velocity is mathematically represented as
=> 
=>
It would be kinetic energy. Let's say the book is weighs 10 Newtons you need to use a force of 10 Newtons to lift the book. In other words it's positive. As you move the book you're giving it energy. Namely potential energy which will turn to kinetic energy if you let it go. So you're changing it's position and energy.
An example would be 2 types of motion. It could be rectilinear or projectile motion. There are various equations for each type. Since you don't want me to tell you the answer, I could just express it in words. Then, it will be up to you to translate into mathematical equations.
For rectilinear motion, the distance traveled is equal to the initial velocity times the time, plus one-half of the acceleration times the square of the time. For projectile motion, the maximum distance is equal to the square of the initial velocity multiplied with the square of the sine of the launch angle, all over twice the gravity.
Answer:
In D: 3J
Explanation:
Potential energy: Ep=mgh where m is the mass, h altitude.
In point A: h=20cm=0.2m
Epa=12=0.2×mg. Thus mg=12/0.2=60N
For point D: hd=5cm=0.05m
Epd=mg×0.05=60×0.05=3J
