What is the weight of a 45 kg box?

Answers

Answer 1

Final answer:

The weight of a 45 kg box, assuming standard Earth gravity, would be 441.45 Newtons, which is calculated by multiplying the mass by the acceleration due to gravity.

Explanation:

The weight of an object is the force due to gravity acting on its mass. It is calculated using the equation Weight = Mass × Gravity. The mass of the box is given as 45 kg, and assuming standard Earth gravity which is approximately 9.81 m/s2, the weight can be calculated as follows:

Weight = 45 kg × 9.81 m/s2 = 441.45 Newtons (N)

Therefore, the weight of a 45 kg box would be 441.45 Newtons under Earth's gravity.

Without inertia, how would an object that is experiencing a centripetal force behave?

It would move in a line away from the circle’s center.
It would move in a line toward the circle’s center.
It would move in a curved, circular path.
It would move in a line tangent to the circular path.

Answers

The correct option is this: IT WOULD MOVE IN A CURVED CIRCULAR PATH.
Objects that are travelling in circular paths change directions all the time as they move round the circle, but they are prevented from moving off in a straight line by centripetal force. The centripetal force keeps pulling the objects towards the center of the circle.

B. It would move in a line toward the circle’s center.

To get an spaceship into orbit, it has to move
about as fast as the speed of sound
about as fast as the speed of light
about 18,000 miles per hour
there is no minimum speed for orbital motion

Answers

The answer is the third option, "about 18,000 miles per hour". If you just want to get a spaceship into orbit around the Earth, the spaceship will need to reach a minimum speeds of about 4.9 miles per second, which is equivalent to 17,600 miles per hour (about 18,000 miles per hour to the nearest thousand).
