Answer:
You will feel more weight if it is accelerating out of the planet.
You will feel less weight if it is accelerating towards the planet.
Explanation:
The weight that you are observing or feeling is basically due to the change in acceleration of your fall or rising up in the spaceship. When the acceleration is stationary on the surface, you experience your normal weight due to the gravitational acceleration of that planet.
When the spaceship accelerates above or out of the planet you experience acceleration more than the acceleration of gravity hence more weight.
When the spaceship accelerates towards the planet you experience acceleration less than the acceleration of gravity hence less weight.
If the spaceship is free falling at the gravitational acceleration you experience a zero weight
The maximum distance that a ball can be thrown at a speed of 20 m/s depends on the angle at which the ball is thrown. In ideal conditions and at a 45-degree angle, the theoretical maximum distance is approximately 40.57 meters.
The question is asking about the maximum distance you can throw a ball given an initial speed, which is a topic in Physics known as projectile motion. In an ideal condition, where air resistance is ignored, the maximum distance a projectile can travel is achieved when it is launched at an angle of 45 degrees.
However, we are missing a piece of information in this situation, which is the launch angle. Without knowing the angle at which the ball is thrown, we cannot accurately calculate the maximum distance. Theoretically, if the ball is thrown at an angle of 45 degrees, the distance (d) can be obtained using the formula for the range of a projectile: d = (v^2)/g, where v is the initial speed and g is the acceleration due to gravity. Substituting the value, d = (20^2)/9.81 = 40.57 meters. But this is an estimation and the value could change according to the actual circumstances when the ball is thrown.

c. the gearbox.
b. the shaft.
d. a brush.
Answer:
a. the rotor
Explanation:
A commutator is a rotary electric switch that periodically changes the direction of the current between the rotor and the external circuit. In a motor provides energy to the rotor. It consists of a cylinder composed of multiple metal contact segments on the rotor.
b. 0 degrees Celsius
c. 10 degrees Celsius
d. 10 degrees Celsius
Answer:so that means the answer 32°F = 0°C
Explanation:
Using (F - 32)/9 = C/5
Where F is Fahrenheit, C = Celsius.
Let F = 32, (32 - 32)/9 = C/5
0/9 = C/5
0 = C/5, therefore C = 0*5 = 0
32°F = 0°C
c. gravitational field strength.
b. inertial mass.
d. weight.
The correct answer is:
c. toward the floor
In fact, we can find the direction of the magnetic force that acts on a positive moving charge by using the right-hand rule:
- index finger: direction of the charge
- middle finger: direction of magnetic field
- thumb: direction of the force
We also have to keep in mind that for a negative charge, we should reverse the direction of the thumb in order to find the correct direction of the force.
In this case:
- index finger: south to north
- middle finger: east to west
- thumb: toward the ceiling
and since the charge is negative, we have to reverse the sign of the thumb, so the magnetic force points toward the floor.
