True or False: Objects that have more mass also have more gravity.
Fantom [35]

Answer:

True

Explanation:

The smaller object usually moves towards the larger object, because the larger object has more mass than the smaller object, so it has a larger gravitational pull.

What will be the restoring force if a spring with a spring constant of 45 newtons per meter is pulled 0.03 meters in the downwar
allsm [11]
To calculate for the force in a spring, we use Hooke's Law which relates force and the displacement of the spring. It is said that the force is directly proportional to the displacement. So, it will have the equation F = kx where k is a constant and it is the spring constant.

F = kx
F = 45 N/m (0.03)
F = 1.35 N

Pls match this I will mark u as brainlist ans​
Tasya [4]

Answer: The items listed in the attached file is correctly matched below.

Explanation:

51.) Temperature --> ( Kelvin). This is the correct option as the standard international unit of temperature is measured in Kelvin.

52.) Needle --> ( wedge). An example of a wedge is a needle as they are simple machine designed to make work easier.

53.) Wood --> ( non - magnetic material). This is the correct option as wood can not be attracted by a magnet.

54.) Door knob--> (wheel and axle). The door knob is a type of wheel and axle as it has a wheel portion which is the knob and an axle which is the rod in the door that turns the same axis.

55.) Ramp --> (inclined plane). A ramp is an inclined plane which has a sloping surface.

56.) Like forces --> (repels each other). In an electrostatic field, two charged objects repels each other if they have like forces.

57.) Mass --> ( kilogram). This is the correct option as the standard international unit of mass is measured in kilogram.

58.) Friction --> ( oppose motion). This is correct as friction is the force that poses resistance to a moving object.

59.) Cobalt coin -->( magnetic material). This is the correct option as cobalt coin can be attracted by a magnet.

60.) Lemon crusher --> ( Class 2 lever). This is correct as the lemon (load) is at the middle of the fulcrum ( squeezer) and the effort (hand)

61.) Sew saw -->( Class 1 lever). This is correct as in first class lever type of machine, the fulcrum is in-between the load and the effort.

62.) Wheel and axle --> ( Grooved wheel with rope around)

63.) Unlike forces --> ( attracts each other). In an electrostatic field, two charged objects attracts each other if they have unlike forces ( that is, one is positive and the other is negative).

64.) Earth pulls everything towards --> (Gravitational force). This is correct as stated by Newton's law of universal gravitation. This law states that every massive particle in the universe attracts every other massive particle with a force which is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.

65.) Wedge --> (Device to split object apart). This is correct as wedge is a type of simple machine which is used to split objects apart.
