How will a skydiver's velocity change when a parachute first
opens?
a The speed will suddenly decrease.
b The direction of the velocity is now upward.
c The acceleration will stay the same.
d The speed will not change.

Answers

Answer 1
A, When the parachute opens, the air resistance increases. The skydiver slows down until a new, lower terminal velocity is reached.
Answer 2
A. When falling from a high speed, opening the parachute will cause the high speeds to slow down and cause you to fall slower hence why the parachute is needed to land safely

3. If an object has kinetic energy what must it be done

Answers

Answer:

when you crank you make kinetic energy and then the kinetic energy makes potential energy.

all moving objects have kinetic energy

An object that has kinetic energy must be in motion

Potential energy is technically stored within matter, though a force must be applied to an object in order for it to store potential energy. However, while the energy itself is stored in the mass of the object, another force (gravitational or elastic) must be present to release the potential energy.

Kinetic energy is the energy an object has because of its motion. If we want to accelerate an object, then we must apply a force. Applying a force requires us to do work. After work has been done, energy has been transferred to the object, and the object will be moving with a new constant speed.

In the important funerary ceremony, a person's heart is balanced against this feather. If it is lighter, it means that they are without sin (pure of heart) and are entitled to join Osiris in the field of reeds for their afterlife. Otherwise, they are eaten by the part-crocodile-part-lion-part-hippo god Ammut and just disappear. 8 people have just arrived to be judged. Fortunately, it is known that only one of them is pure of heart, whilst the remaining 7 are sinners, and have heavier hearts (but all sinners' hearts weigh the same as each other). Help Anubis identify the lightest of the 8 hearts, using just the hearts and a balance. But beware! Ammut grows impatient: you may only use the balance twice!
