Answer:
Explanation:
d = Diameter of typical neutron star = 20 km = 20000 m
D = Distance between Earth and Moon =
Here, so we use small angle approximation
The angular diameter of the neutron star would be from Earth.
Answer:
Explanation:
Kinetic energy can be found using the following formula:
where <em>m </em>is the mass and <em>v</em> is the velocity.
The mass of the ball is 0.5 kilograms and the velocity is 15 meters per second
Substitute the values into the formula.
First, evaluate the exponent.
- (15 m/s)²= (15 m/s) * (15 m/s) = 225 m²/s²
Multiply 0.5 kg by 225 m²/s²
Multiply 112 kg*m²/s² by 1/2, or divide by 2.
- 1 kg*m²/s² is equal to 1 Joule
- Therefore, our answer of 56.25 kg*m²/s² is equal to 56.25 Joules.
The kinetic energy of the ball is <u>56.25 Joules</u>
Answer:
2.064 N.m
Explanation:
Torque: This is the force that act on a system, which tends to cause rotation or twisting. The S.I unit of Torque is N.m
Torque is represented mathematically as,
T = F×d........................ Equation 1
Where T = Torque, F = Force, d = perpendicular distance.
Given: F = 4.8 N, d = 0.43 m.
Substitute into equation 1
T = 4.8×0.43
T = 2.064 N.m
Hence the Torque produced = 2.064 N.m

Answer:
B.) Greater than one
(at least I am pretty sure I am sorry if I am wrong I tried my best)
Explanation:
I think it is greater than one because it moves a short distance but it still is very helpful. The doorknob doesn't do much it just turns over and opens up a door. But, a doorknob CAN do much more. A doorknob can lock and keep things that you don't want inside out. It can also keep a door closed.
