if the mass is 10 gram and the volume is 7 cubic centimetre,find the density in kilogram per cubic metre

The cyclist must be fed in order to continue to pedal because food will

provide him/her with energy to continue with it.

Cycling and other forms of activities involve the use of energy by the body ton perform them and the energy dwindles with time which is why we eat everyday to gain more energy.

The cyclist will have to eat foods such as carbohydrates so as to have more

energy to continue to pedal.

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] .

Explained in explanation section

Explanation:

There are different classes of psychologists but for the purpose of this question we need just 7 that would fit into the study of love. These 7 will be;

1) A behavioral Psychologist might study behaviors associated with love, such as hugging, caressing or kissing.

2) A psychodynamic psychologist might study how a people's challenges with love are caused by unmindful and unresolved conflicts.

3) A biological psychologist might study which chemicals in the brain such as dopamine make people feel loved. He might also study parts of the what parts of the brain are active when people are in love.

4) A cognitive psychologist might study how people's cognitive processes will change when they are in love.

5) An evolutionary psychologist might study how certain actions or behaviors associated with love provided our forefathers with sufficient knowledge to handle their love problems.

6) A sociocultural psychologist might study how people express love in in various cultures across the world.

7) A humanistic psychologist might study the behavior of those who feel most loved and the impact it has in their lives

Answer:

A psychodynamic psychologist might study how a person's problems with love are caused by unconscious, unresolved conflicts. A behaviorist might study observable behaviors associated with love, such as hugging or kissing. A cognitive psychologist might study how a person's cognitive processes change when one is in love.

Answer:

I believe its C

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.

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

Answer:

The answer is Kinetic Energy

Explanation:

Kinetic energy is the term describes the energy an object has because of its motion. Option C is correct

The energy of the body by the virtue of its motion is known as the kinetic energy of the body. It is defined as the product of half of mass and square of the velocity.

KE =1/2mv²

Where,

m is the mass

KE is the kinetic energy

v is the velocity of the body

The word "kinetic energy" refers to the energy that an item possesses as a result of its motion.

Hence option C is correct.

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.

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.

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]

Answer: Sound

Explanation: it's asking which of the following is a result of transfer of energy and sound comes from vibrations

Answer:

0.613 milliseconds

Explanation:

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.

Answer:

220.46 lbs

Multiply the mass by 2.205 for an approxinate result.

The answer is 220.462.

Answer:

first you have to organize the data. a=acceleration t=time v0=inicial velocity vf=final velocity

a=2.92m/s2

t=5.1s

vf=?

v0=0

now the formula you have to use is: vf=vi+a*t (final velocity equals to inicial velocity plus acceleration times time)
