Which is heavier , a kilogram of lead or a kilogram of a polystyrene beads ?​

Answers

Answer:

They weight the same, they're both 1 kilogram

The weight of the given objects is the same since they have equal mass.

Weight of object

The weight of an object is the gravitational pull of earth on the object. Weight is vector quantity because it varies from place to place due to difference in acceleration due to gravity.

The weight of 1 kg lead

W = mg

W = 1 x 9.8

W = 9.8 N

The weight of 1 kg polystyrene

W = mg

W = 1 x 9.8

W = 9.8 N

Thus, the weight of the given objects is the same since they have equal mass.

If the radius of Earth were one half what it is now, and the mass were the same, what would be the value of g?

Answers

Answer:

4 times what it is now.

Explanation:

g=G(M/r^2)

G is constant, so ignore.

We have (1M/0.5r^2), or 4.

Answer:

4g

Explanation:

the equation of g (field gravity)

g = G M/R²

because G (Contant of Gravitasion) and M (Mass of earth) same, them

g2/g1 = R1²/R2²

g1 = g now

g2 = g which the value we looking for

g2/g = 1/(1/2)²

g2/g = 1/(1/4)

g2/g = 4

g2 = 4g

The earth rotates on its axis from west to east. Therefore, all the stars in the sky (except the pole star) seem to move from east to west. Pole star is located along the axis of rotation of the Earth in the north direction. Thus, it seems to remain stationary at a point in the sky and all other stars appear to move around the pole star.

What do the arrows in this photograph represent?
A. Gravity and air resistance
B. An action-reaction force pair
C. A pair of unbalanced forces at work
D. Friction and air resistance

Answers

Answer: B An action-reaction force pair

Explanation: Took the exam

The arrows in this photograph represent: An action-reaction force pair. Hence, option (B) is correct.

What is  action-reaction force pair?

When two bodies interact, they exert an equal and opposite force on one another in accordance with Newton's third law of motion. Action-reaction forces are made up of these forces.

"When one body exerts a force on the other body, the first body experiences a force that is equal in magnitude in the opposite direction of the force which is exerted," according to Newton's third law of motion.

According to the above assertion, there are always two forces operating on the objects involved in an interaction. The forces are of identical magnitude, but the direction of the force acting on the first object is different from the direction acting on the second.

Answers

Answer: A. An ice hockey player picks up a trophy as he slides past it

Explanation:

A PE X

The statement that best describes a perfectly inelastic collision is

C. A surfer falls off of his surfboard when a wave hits him.

What is collision?

A collision is the interaction between two bodies in such a way that the momentum and velocity of one body gets changed due to the presence of other body. There are three types of collision-

1. Elastic collision

2. Inelastic collision

3. Perfectly inelastic collision.

In all types of collision , the momentum of the system before collision and after collision always remains same or we can say that momentum is conserved in collisions

What is elastic collision

An elastic collision is the one in which kinetic energy is also conserved and coefficient of restitution is one. Both the bodies move separately with different velocities after elastic collision.

What is inelastic collision ?

In inelastic collision  there is a loss of kinetic energy and coefficient of restitution is less than one.

What is perfectly inelastic collision?

In perfectly inelastic collision there is maximum loss of kinetic energy and coefficient of restitution is zero. Both the bodies stick together after collision and move with same velocity

What is coefficient of restitution ?

Coefficient of restitution is the  ratio of  relative velocity of separation after collision to relative velocity of approach before collision.

A surfer falls of his surfboard when a wave hits him is an example of perfectly inelastic collision because in this when water hits the surfers he falls of and sticks to the water , and will also now move with the velocity of water .

So  when the surfer falls off his surfboard when a wave hits him is perfectly inelastic collision.

Calculate its volume in m?,
b. The mass of the concrete slab is 180 kg. Calculate its density in kg/m.
3.
a.

Answers

Explanation:

formula: Mass

Density x volume

2a) m=10kg v=0.3m³

10÷0.3=33.3 kg/m

2b) m = 160 kg V=0.1m³

160÷0.1=1600 kg/m

2c) m = 220 kg V = 0.02m³

220÷0.02=11000 kg/m

A wooden post has a volume of 0.025 and a mass of 20kg. Calculate its density in kg/m.

density = volume ÷ mass

20÷ 0.025=800 kg/m

Challenge: A rectangular concrete slab is 0.80m long, 0.60 m wide and 0.04m thick. Calculate its volume in .

Formula : Length x width x height = Volume

0.80 x 0.60 x 0.04 = 0.0192m³

B) The mass of the concrete slab is 180 kg. Calculate its density in kg/m.

density = volume ÷ mass

180 ÷ 0.0192 = 9375 kg/m
