In her dissertation research, a graduate student finds a correlation of +0.95 between two of the variables being studied. How should she interpret this correlation coefficient

Answers

Answer:

Explanation:

A correlation of +0.95 between two variables signifies a strong positive relationship between the two measured variables (the dependent and independent). The value is usylay called the correlation Coefficient (r) as it measures the level or degree of relationship or correlation between two measured linear variables. The value ranges between - 1 and +1 with + signifying a positive relationship (increase or decrease in one variable leads to corresponding increase or decrease in the other) while a negative correlation means (a decrease in A leads to increase in B and vice versa). A correlation Coefficient of 0 means no relationship and the strength of the relationship increases as the value approaches - 1 or +1.

Let G be the garvitational constant and R be the radius of earth. If the radius of the earth becomes half, the new value of gravitational constant will be

Answers

Answer:

G = 1.670 × [tex]10^{-11}[/tex] [tex]m^{3}kg^{-1}s^{-2}[/tex]

Explanation:

From Newton's law of universal gravitation,

F = [tex]\frac{GMm}{R^{2} }[/tex]

Where F is the force of attraction, G is the gravitational constant, M is the mass of the earth, R is the radius of the earth.

From Newton's second law of motion,

F = mg

mg = [tex]\frac{GMm}{R^{2} }[/tex]

g = [tex]\frac{GM}{R^{2} }[/tex]

⇒    G = [tex]\frac{gR^{2} }{M}[/tex]

If the radius of the earth becomes half,

R = [tex]\frac{R}{2}[/tex], then;

G = [tex]\frac{gR^{2} }{4M}[/tex]

Given that: g = 9.8 m/[tex]s^{2}[/tex], radius of the earth is 6371000 m, mass of the earth is 5.972 × [tex]10^{24}[/tex]kg, then;

G   = [tex]\frac{9.8*(6371000)^{2} }{4*5.972*10^{24} }[/tex]

   = 1.670 × [tex]10^{-11}[/tex] [tex]m^{3}kg^{-1}s^{-2}[/tex]

9. Carlos jumps out of a hovering helicopter. After he opens his parachute, his acceleration due to gravity decreases

to zero. This is because

A The force of air resistance becomes equal in magnitude to his weight.

B. The force of gravity has become zero.

C. Air resistance must be zero

D. He must have struck the ground,

Answers

Answer:

A The force of air resistance becomes equal in magnitude to his weight.

Explanation:

When Carlos jumped out of the helicopter, he fell with a downward force which is proportional to his weight.

His weight is the product of his mass and acceleration due to gravity.

When the parachute is deployed, air resistance between the air molecules and the surface area of the parachute generates a drag force, which acts upwards.

If the drag forces exceeds his weight, then his net force will be directed upwards.

If his weight exceeds the drag forces, then the net force on his body will be downwards.

In the case that his drag force, and his weight are equal, there will be a zero net force on him, and he will experience no acceleration.

So, if after he opens his parachute, his acceleration due to gravity decreases  to zero, then we can say that this is because  the force of air resistance (drag) becomes equal in magnitude to his weight.

Does the horizontal distance d travelled by the ball depend on the height of release? If it does depend on the height, what is the mathematical relationship between the variables

Answers

Answer:

Explanation:

Yes , the horizontal distance travelled by the ball will depend upon the height of release .

When a ball is thrown at some angle from a height , it has two components , the vertical component and horizontal component . The ball goes in horizontal direction due to its horizontal component . Its vertical component has no role to play .  But the horizontal range covered by the body thrown

depends upon the duration of time in which it remains in air . The longer it remains in air , the greater distance it can cover horizontally .

Horizontal distance covered = t x horizontal velocity

If V be the velocity of throw and Vx be its horizontal component

Horizontal distance covered = t x Vx

Now t depends upon the height . If height rises , time of fall will increase so horizontal distance covered will increase .

If h be the height from which the body is thrown , Vy be the vertical upward component of initial velocity

from the relation

s = ut + 1/2 at²

h = - Vy t  + 1/2 at²

As h increases , t will increase and therefore horizontal distance covered will increase. If the ball has only  horizontal velocity initially , Vy = 0

h = 1/2 gt²

[tex]t = \sqrt{\frac{2h}{g} }[/tex]

Horizontal distance covered  = t x Vx

= [tex]\sqrt{\frac{2h}{g} } \times V_x[/tex]

From this expression also

Horizontal distance covered is proportional to [tex]\sqrt{h}[/tex] .

1) Describe the motions of the moon relative to the Earth and the sun. Explain how this causes us to see phases of the moon, and identify these phases by name.

Answers

Answer:

Explanation:

The moon is a natural satellite of the earth, which performs rotational and revolutionary motions simultaneously. As the earth rotates about its axis, the moon rotates round it. But revolves round the Sun, as the earth also revolves round the Sun.

The motion of the moon causes series of its phases. Some major phases of the moon are, new moon, 1st quarter, full moon, and 3rd quarter (last quarter).

Since the moon reflects the light from the Sun, the face of the moon reflecting the light from the Sun changes gradually with respect to its motion.

At new moon, the face of the moon reflect no light. But reflects 100% at full moon. While both 1st and 3rd quarters show partial reflections.

A jogger runs 3 miles east then 7 miles west what is her displacement

Answers

Answer: 4 miles.

Explanation:

Let's use the rectangular coordinates (x,y)

And define:

East as the positive x-axis.

North as the positive y-axis.

We know that, if the jogger starts at the point (0mi, 0mi):

"Runs 3 miles East"

Then the new position is (3mi, 0mi)

"Then 7 miles west"

The new position is (3mi - 7mi, 0mi) = (-4mi, 0mi)

Now, the displacement is calculated as the difference between the initial position and the final position, and this can be written as:

D = I (-4mi, 0mi) - (0mi, 0mi)I = √( (-4mi - 0mi)^2 + (0mi - 0mi)^2) = 4mi

The total displacement is 4 miles.

Given that a rock is thrown vertically upward at an initial velocity of 70 m/s. What is the approximate acceleration of the rock when it reaches its maximum height

(assume upward is the positive y direction)?

Since the reached the maximum height, the final velocity V will be equal to zero.

Using the first equation of motion to find the time.

And since it is a vertical direction, and not horizontal, the acceleration a will be equal to zero.

Yvette drops her cell phone as she is getting out of the truck one day she noticed that the cell phone fell 1.5m to the ground how fast was the phone moving right before hitting the ground

Answers

Answer:

The speed was 5.42 m/s

Explanation:

The height of fall of the phone s = 1.5 m

The phone was at rest in her hand, so the initial velocity u = 0 m/s

The velocity right before the phone strikes the ground v = ?

Using the equation

[tex]v^{2}[/tex] = [tex]u^{2}[/tex] + 2gs

where

g is the acceleration due to gravity = 9.81 m/s^2

substituting values, we have

[tex]v^{2}[/tex] = [tex]0^{2}[/tex] + 2(9.81 x 1.5)

[tex]v^{2}[/tex] = 29.43

v = [tex]\sqrt{29.43}[/tex] = 5.42 m/s
