A 17-N falling object encounters 9 N of air resistance. The magnitude of the net force on the object is

Correct option is A)  The objects always attract each other.

There is always a pull from gravity. It won't repel.

A mass attracts a mass; the amount of the gravitational force is directly proportional to the masses of the two items and inversely proportional to the square of the distance between the two objects. Gravitational force is an attractive force that exists between all objects with mass.

A rise in one quantity causes a fall in the value of the other since the two values are inversely proportionate. In other words, as the separation distance increases, the force of gravity decreases, and as the separation distance decreases, the force of gravity increases.

Answer:

Speed is the measure of how fast something moves

Explanation:

When the amplitude of a body undergoing simple harmonic motion is doubled then the maximum speed is doubled.

Equation of shm is

x(t) = Xo + Acos(wt + f)

Differentiate it with t

v(t) = wA * sin(wt + f)

Then max speed Vmax is wA

So by above relation if we double the amplitude then velocity will be doubled.

If the force acting on the oscillating body is always in the direction opposite to the displacement of the body from the equilibrium or the mean position and its magnitude is proportional to the magnitude of displacement, the body is said to be executing SHM.

If the displacement vs. time curve of the oscillating body is sinusoidal in nature, the body is said to be executing SHM. This is another definition of SHM.

If the potential energy of the oscillating body is proportional to the square of its displacement with reference to the mean position, the body is said to be executing SHM. This is yet another definition of SHM.

The magnitude of the torque will increase as the angle between the force and the line of action of the torque approaches 90 degrees.

Torque is a measure of the rotational force acting on an object and is defined as the product of the force and the distance from the axis of rotation to the point where the force is applied. The torque is also proportional to the sine of the angle between the force and the line of action of the torque.

When the angle between the force and the line of action of the torque is 0 degrees, the torque is zero, as the force is acting in the same direction as the line of action of the torque. As the angle increases, the torque increases and reaches its maximum value when the angle is 90 degrees, at this point the sine of the angle is 1, so the torque is at its maximum value.

In practical terms, if you imagine a door knob, when you push or pull the door knob closer to 90 degree angle with the door, it will be harder to open or close the door, than when you push or pull the door knob at a small angle.

The distance traveled before the car comes to a stop is 66.66 m. It's important to note that the negative sign on acceleration indicates that the car is slowing down.

To find the distance traveled before the car comes to a stop, we can use the formula for distance traveled under constant acceleration. The formula is:

Distance = initial velocity * time + (1/2) * acceleration * time^2

The car is traveling at an initial velocity of 20 m/s and the acceleration is given by the function -6.0t, where t is the time in seconds.

We can find the time it takes for the car to come to a stop by setting the final velocity to 0 and solving for t.

0 = 20 + (-6.0)t

t = 20/6

t = 3.333 s

Now that we have the time, we can substitute it back into the distance formula along with the initial velocity and acceleration:

Distance = 20 * 3.333 + (1/2) * -6.0 * (3.333)^2

Distance = 66.66 m

The reaction distance for a vehicle traveling at 60 mph on the highway is 312 feet, and the reaction distance for a vehicle traveling at 80 mph is 496 feet. Simply put, at current speeds, doubling the car's speed will result in a three-fold increase in stopping distance.

Seeing the fur rubbed with the rod attracts neutral paper, this happens because the friction of the rod with the rubbed can produce a static electric force. It is this static electric force that causes the pieces of paper to be attracted and rod up.

When you rub a plastic ruler over your hair, it becomes electrically charged, causing the paper to pull and stick.

The electric charge consists of two types of charge, namely negative charge, and positive charge. However, some objects have an equal amount of negative charge and positive charge. Objects that have the same amount of positive and negative charges are called neutral objects. Initially, a plastic ruler is also an electrically neutral object.

A Shuttle astronaut is sent to repair a defective relay in a 600. 00- kg satellite that is traveling in space. The combined velocity when the astronaut grabs hold of the satellite is 17,004.4 m/s.

The combined velocity of the astronaut and the satellite when the astronaut grabs hold of the satellite is the relative velocity between the two objects. The relative velocity can be calculated using the principle of conservation of momentum. The principle states that the total momentum of an isolated system remains constant if no external forces act on it.

The initial momentum of the satellite is

= (600.00 kg) * (17,000.0 m/s)

= 10,200,000 kg*m/s

The initial momentum of the astronaut and the MMU is

= (400.00 kg) * (17,010.0 m/s)

= 6,804,400 kg*m/s

The final momentum of the combined system is

= (600.00 kg + 400.00 kg) * v,

where v is the final velocity of the combined system.

The conservation of momentum equation:

=> initial momentum = final momentum

= 10,200,000 kgm/s + 6,804,400 kgm/s

= (1000 kg) * v

= v

= (10,200,000 + 6,804,400) / 1000

= v

= 17,004.4 m/s

So, the combined velocity of the astronaut and the satellite when the astronaut grabs hold of the satellite is 17,004.4 m/s.
