what does point c represent

Answer:

9.80 kg

Explanation:

F = ma

96 N = m(9.8 m/s^2)

m = 9.80 kg

The mass of the ball will be m= 9.8 kg

It states that the force is equal to the rate of change of momentum . For a constant mass , force is equal to mass times acceleration

given :

Force due to gravity = 96 N

g = acceleration due to gravity = 9.8 m /s^2

using Newton's second law of motion

Since , F = ma

          96 = m g

          m = 96/9.8

          m= 9.8 kg

The mass of the ball will be m= 9.8 kg

Answer:

La Niña, because the jet stream is displaced northwards

Explanation:

La Nina is known to be a cool phase that affects the average ocean temperature. During this period the surface wind becomes stronger and there is lesser rainfall over the areas of the central tropical Pacific to which the Southern United States belongs.

Hence, when the southern United States experiences periodic occurrences of severe cold and drought conditions, the weather phenomenon most likely causes this and why is "La Niña, because the jet stream is displaced northwards."

Answer:

The time it will take for the car to reach a velocity of 28 m/s is 7 seconds

Explanation:

The parameters of the car are;

The acceleration of the car, a = 4 m/s²

The final velocity of the car, v = 28 m/s

The initial velocity of the car, u = 0 m/s (The car starts from rest)

The kinematic equation that can be used for finding (the time) how long it will take for the car to reach a velocity of 28 m/s is given as follows;

v = u + a·t

Where;

v = The final velocity of the car, v = 28 m/s

u = The initial velocity of the car = 0 m/s

a = The acceleration of the car = 4 m/s²

t = =The time it will take for the car to reach a velocity of 28 m/s

Therefore, we get;

t = (v - u)/a

t = (28 m/s - 0 m/s)/(4 m/s²) = 7 s

The time it will take for the car to reach a velocity of 28 m/s, t = 7 seconds.

10 minutes on the stove, the water molecules in the pot are in two different states , the two different states are the liquid state and the gaseous state.

Anything which has mass and occupies space is known as matter, mainly there are four states of matter solid liquid gas, and plasma .

These different states of matter have different characteristics according to which they vary their volume and shape .

As given in the problem 10 minutes on the stove , the water molecules in the pot are in two different states , the two different states are liquid state and the gaseous state ,

The gaseous state of the water molecules has higher energy and then motion as compared to the liquid state of the water molecule .

Answer:

The correct answer is -

1. 67500 J

Explanation:

The formula for KE is  

K.  E.  =  1/ 2 *m v ^2  

So input the values we know:

K . E.  =  1/2 ⋅*150  *30 ^2

K . E.  =  150 * 900 /2

K . E . =  67500  

K . E.  = 67500

If the velocity is double then;

use 2v in the formula

K.  E.  = ( 1/ 2 )*m(2 v) ^2

= (1/2)*4m v ^2

it is four times to original Kinetic energy, and similarly if tripled then, it will be 9 times to original.

The owl eats 42 prey in a week and 180 prey in a month.

To calculate how much the owl eats in a week and a month, we need to determine the number of prey consumed in each time period.

In a week:

The owl produces two pellets every 24 hours. So, in one day, it consumes 2 * 3 = 6 prey (since each pellet contains the remains of 3 prey).

In a week (7 days), the owl consumes 6 * 7 = 42 prey.

In a month:

Assuming a month has 30 days (though some months have 31 days or 28/29 days), we can calculate the number of prey consumed in a month.

In a day: 6 prey

In a month (30 days): 6 * 30 = 180 prey.

Hence, the owl eats 42 prey in a week and 180 prey in a month.

The statement itself is true. But to be completely and compulsively correct, that's Newton's FIRST law of motion, not the third.

It is evident that the force due to gravity exerted on the moon is not constant because the  moon’s distance from the planet is always changing.

The gravitational force is the force of attraction that brings two masses together in the universe. We have to note that the gravitational force is an attractive force and that all of the objects that are found on the surface of the earth are under the gravitational filed of the earth.

Now we know that the distance that exists between the the moon as it is orbiting round the sun is always changing. We know that the gravitational force depends on the masses as well as the distance.

Answer:

Blood circulation

Explanation:

The process being described is the circulation of blood.

Oxygen-rich blood leaves the heart through arteries and is transported to various cells and tissues where the exchange of oxygen for carbon dioxide takes place. Thereafter, the oxygen-deficient/carbon dioxide-rich blood moves into the veins and returns to the right side of the heart before traveling to the lung. In the lung, the carbon dioxide in the blood is exchanged for oxygen before the blood enters the left side of the heart and circulated all over again.

Answer:

Repel each other.

Explanation:

Van de Graaff generator is a device that was invented in 1929, by an American physicist called Robert J. Van de Graaff.

A Van de Graaff generator refers to an electrostatic generator that typically involves the use of a moving belt to accumulate electric charge on a hollow globe that is made from metal placed on top of an insulated column and thereby, creating very high electric potentials i.e very high voltage-direct current (DC) electricity at low current levels.

Generally, when we touch a Van de Graaff generator, our hair may stand up if it is dry. This happens only if the strands of our hair repel each other because they are like charges i.e having the same potentials.

magnetism and dipole-dipole interaction

Explanation:

Two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.

The attraction between two magnets varies, and that depends upon several factors such as the strength of the force of attraction, which determines the usefulness and functionality of magnets, for example, in industrial settings, strong magnets are often used to lift heavy loads, etc.

Hence, two magnets are attracting each other, one magnet is big and strong, the other is small and weak, the big magnet attracts the small magnet with a stronger force, and the attraction depends on the size of the magnet.
