Answer:

The acceleration the ball gets = 30 m/s²

Explanation:

The given parameters are;

The mass of the first ball that hits an object, m₁ = 0.35 kg

The mass of the object hit by the ball, m₂ = 7 kg

The acceleration given to the second object, a₂ = 1.5 m/s²

Let the a₁ represent the acceleration the ball gets

Newton's third law states that action and reaction are equal and opposite, therefore, the force exerted on a body A by a body B is equal to the force exerted on the body B by the body A;

Therefore, we have;

The force exerted on the object, F₂ = m₂ × a₂ = 7 × 1.5 = 10.5 N

The force the ball exerts on the object = F₁ = m₁ × a₁ = 0.35 × a₁

By Newton's third law, F₁ = F₂, which gives;

m₁ × a₁ = m₂ × a₂

0.35 × a₁ = 10.5

a₁ = 10.5/0.35 = 30

The acceleration the ball gets = a₁ = 30 m/s².

Answer:

The phases are the first and third quarters.

Explanation:

During the first quarter of the moon phases, the line between Earth and the Sun is at a right angle to the line between Earth and the moon. At this time the moon has completed the first quarter of its orbit around the earth. At this point, half of the moon is fully reflecting light from the sun.

Also during the third quarter which is the last quarter, the line between the earth and the sun is at a right angle to the line between the earth and the moon. This is the time when the second half of the moon which was not illuminated during the first quarter becomes completely illuminated.

Answer:

It produces 1000Ω.

Explanation:

You have to apply Voltage formula, V = I × R :

V = I × R

6 = 0.006 × R

R = 6 ÷ 0.006

R = 1000Ω

We have that from the Question"How much resistance allows 6V battery to produce a current of 0.006 amps?" it can be said that  How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms

From the Question we are told

How much resistance allows 6V battery to produce a current of 0.006 amps?

Generally the equation for Resistance mathematically given as

[tex]R=\frac{V}{I}\\\\\Therefore\\\\R=\frac{V}{I}\\\\R=\frac{6}{0.006}\\\\[/tex]

R=1000 ohms

Therefore

How much resistance that allows 6V battery to produce a current of 0.006 amps is

R=1000 ohms

Answer:

R = 9.58 m/s

Explanation:

cos(37) = (7.65 m/s)/R

R = (7.65 m/s)/cos(37)

R = 9.58 m/s

Answer:

t = 4 [s]

Explanation:

To solve this problem we must use the following equation of kinematics.

[tex]v_{f}=v_{o}+a*t[/tex]

where:

Vf = final velocity = 16 [m/s]

Vo = initial velocity = 0

a = acceleration = 4 [m/s²]

t = time [s]

Now replacing:

[tex]16=0+4*t\\t = 16/4\\t = 4[s][/tex]

Answer:

7.5 m/s

Explanation:

A red tailed hawk leaves its nest and flies 100 meters across the sky in 20 secs

Speed 1= distance/time

= 100/20

= 5m/s

When it spots a garter snake on the ground it flies 50 meters in 5 secs

Average speed= distance /time

= 50/5

= 10 m/s

Therefore the average speed of the hawk over the entire journey can be calculated as follows

= 10+5/2

= 15/2

= 7.5 m/s

Answer:

5 sec

Answer:

learning and memory are very closely related concept . Learning is the acquisition of silk or knowledge, while memory is the expression of what you've acquired.Another difference is the speed with which the two things happen if you acquire the new skill or knowledge slowly and laboriously, that's learning

Answer: I took a test that had this question and the answer was Memory is the foundation of all learning. I hope this helps

Explanation:

Answer:

F' = 9F

Explanation:

The electric force between charges is given by :

[tex]F=\dfrac{kq_1q_2}{r^2}[/tex]

It means,

[tex]F\propto \dfrac{1}{r^2}[/tex]

If distance decreased by a factor of 3, r' = r/3

Net force will become,

[tex]F'=\dfrac{kq_1q_2}{r'^2}\\\\=\dfrac{kq_1q_2}{(\dfrac{r}{3})^2}\\\\=9\dfrac{kq_1q_2}{r^2}\\\\=9\times F[/tex]

It means new force will become 9 times that of the initial force.

Answer:

it is increased by a factor of 9
