Gravitational field exists in the space surrounding a charged particle and exerts a force on other charged particles. Gravitational waves are ripples of waves travelling outward from the source. The more massive the orbit of two bodies, the more it emits gravitational wave. And everything around it that is near within the wave experiences a ‘pull’ toward the orbiting bodies.

Electrical Field is the correct answer.
Explanation:
5.00 N
1440 N
1490 N
A nurse applies a horizontal force of 147 N on a bed that has a mass of 152 kg. The magnitude of the normal force acting on the bed is 1490 N.
A force is an effect that can alter an object's motion according to physics. An object with mass can change its velocity, or accelerate, as a result of a force. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction.
The force applied by the nurse is horizontal, so there's no vertical component.
Therefore, the normal force is simply equal to the weight of the bed.
N = mg
N = (152 kg) (9.8 m/s²)
N = 1490 N

Answer:
1490 N
Explanation:
The force applied by the nurse is horizontal, so there's no vertical component.
Therefore, the normal force is simply equal to the weight of the bed.
N = mg
N = (152 kg) (9.8 m/s²)
N = 1490 N
Answer:
They collide, couple together, and roll away in the direction thatthe 2m/s car was rolling in.
Explanation:
We should start off with stating that the conservation of momentum is used here.
Momentum = mass * speed
Since, mass of both freight cars is the same, the speed determines which has more momentum.
Thus, the momentum of the 2 m/s freight car is twice that of the 1 m/s freight car.
The final speed is calculated as below:
mass * (velocity of first freight car) + mass * (velocity of second freight car) = (mass of both freight cars) * final velocity
(m * V1) + (m * V2) = (2m * V)
Let's substitute the velocities 1m/s for the first car, and - 2m/s for the second. (since the second is opposite in direction)
We get:
solving this we get:
V = - 0.5 m/s
Thus we can see that both cars will roll away in the direction that the 2 m/s car was going in. (because of the negative sign in the answer)
new terminal velocity of 10 m/s. She falls at that speed for 3 seconds before landing on the ground.
Sketch the following graphs:
Position vs. Time
Velocity vs. Time
Acceleration vs. Time
During freefall, the position and velocity of the skydiver increase at a constant rate until reaching terminal velocity. After opening the parachute, the position and velocity decrease to a new terminal velocity. The acceleration is constant during freefall and becomes negative when the parachute slows the skydiver down.
Position vs. Time:
During the first 5 seconds, the skydiver is in freefall and her position increases at a constant rate. After opening the parachute, her position still increases but at a slower rate due to the decrease in terminal velocity. When the parachute slows her down, the position increases at a slower rate again. The position remains constant during the final 3 seconds as the skydiver lands on the ground.
Velocity vs. Time:
During the freefall, the velocity of the skydiver steadily increases until it reaches the terminal velocity of 50 m/s. After opening the parachute, the velocity decreases to the new terminal velocity of 10 m/s. The velocity remains constant until the skydiver lands.
Acceleration vs. Time:
At the start of the jump, the skydiver experiences a constant acceleration due to gravity. After reaching terminal velocity, the acceleration becomes zero since there is no net force acting on the skydiver. When the parachute is opened, the skydiver experiences a negative acceleration due to air resistance, slowing down until the new terminal velocity is reached. The acceleration then becomes zero until the skydiver lands.

A government agency constructs a dam.
Patents and copyrights are issued by the government.
Regulations require that cigarette packages advise consumers of health risks.
The correct answer is PATENTS AND COPYRIGHTS ARE ISSUED BY THE GOVERNMENT.
A government is said to be encouraging innovation if it takes special steps to encourage the citizen to be creative in their endeavors. Innovation is one of the key ingredient that a nation needs to grow and it is the responsibility of the government to promote it. By issuing patents and copyright, a government can encourage the citizen to be original in their works and to produce new things.
