Acceleration will only speed up an object?true or false

Answers

Answer 1
Answer: False, yes acceleration does speed up an object but, if an object is slowing down it has a negative acceleration, also if an abject is at a constant speed it will have zero acceleration (example: a brick dropped from a plane will stop accelerating whilst still falling when it reaches terminal velocity (a constant speed))

How could you increase the gravitational potential energy of an object without changing its mass and gravity?A. Make the object larger
B. Raise the object farther off the ground
C. Lower the object towards the ground
D. Allow the object to roll on the ground​

Answers

Answer:

B Raise the object farther off the ground

Final answer:

To increase the gravitational potential energy of an object without altering its mass or gravity, you would need to raise the object to a greater height. The potential energy is determined by the object's mass, its height, and the gravitational force, as shown by the formula potential energy=mgh.

Explanation:

To increase the gravitational potential energy of an object without changing its mass and gravity, you could raise the object farther off the ground. This is because gravitational potential energy is a function of an object's mass, height, and acceleration due to gravity, as represented by the formula potential energy = mgh, m being mass, g being gravity, and h being height.

Moving the object to a greater height without acceleration or carrying the object with or without acceleration at the same height will not result in an increased potential energy. Only by raising the object to a higher position or altitude, you increase its potential energy.

In essence, the principle involves work done against the gravity. When an object is raised to a higher elevation, work is done against gravity. This work gets stored as potential energy in the object-Earth system. Thus, the higher the position of the object, the higher would be its gravitational potential energy.

A 600 kg car is at test and then accelerated to 5m/s , what is its original kinetic energy

Answers

Answer:

0 J

Explanation:

Kinetic energy is defined as:

KE = 1/2 m v²

where m is mass and v is velocity.

The car starts at rest, so it has zero velocity.  Therefore, its initial kinetic energy is 0 J.

The weight of a body floating in a liquid is​

Answers

Answer:

The apparent weight is the weight of the body minus the weight of the liquid displaced. The body will float only when both the weights are same. In this case, the given body of weight W is floating and hence the apparent weight is zero.

Answer:

Zero

Explanation:

The apparent weight is the weight of the body minus the weight of the liquid displaced. The body will float only when both the weights are same. In this case, the given body of weight W is floating and hence the apparent weight is zero.

People working in nuclear plants wear special monitoring devices to track their exposure to radiation. Radioactive materials used in plants emit particles but they also emit high energy waves that are potentially lethal to human life. These waves are ______ waves

Answers

Answer:

Gamma rays

Explanation:

Gamma rays are usually defined as a type of electromagnetic radiations, that are characterized by the presence of shorter wavelength and higher energy. These are the common radiations that are released from the radioactive substances, where an unstable nucleus of an atom releases an excess amount of energy by undergoing continuous electromagnetic processes.

These are harmful to humans and other organisms, as they are comprised of very high energy and they can easily penetrate through the bodies of humans and other organisms.

These gamma particles are emitted in the power plants, where the people working in it wear a special type of device that helps them in monitoring the exposure to radiation.

It could also be gamma rays i don't really know

What did William Penn think would attract new settlers to his colony in Pennsylvania?

Answers

The biggest thing that would attract them to Pennsylvania would be freedom for religious practices. He was a quaker, which is a type of a Christian, but wasn't very liked by Dutch and German and other types of Christians because he wasn't catholic or protestant. So he made a new colony where people would have religious freedom.
