Answer:

weight of two people

Explanation:

Suppose two people are walking and among the two people, if one is heavier than the other, then the one weighing heavier will walk slower because the acceleration of the person weighing lighter is greater.

2nd Law: F=ma

a= change in velocity/time

a=F/m

say both objects must accelerate at a=2 m/s^2

object A is a wood plank, which is roughly 10 kg

object B is my metal ball, which has a mass of 100kg

now, solving for F applied to both objects

Fwood=(10kg)(2 m/s2)= 20 N

Fmetal=(100kg)(2 m/s2)= 200 N

the F needed to move the metal ball is 10 times greater than the F needed to move the wood plank. Hope this helped, I'm about to go fail my physics exam :)

the answer should be and electric current

The rate of flow of electric charge is Electric Current.

The flow of the electricity in a electrical circuit by calculating the amount of electricity flows in the circuit is known as Electric current. The Electric current can be referred by the symbol 'I'. The unit of electric current is Ampere (A).

Some of the characteristics of Electric current are:

The Electric current can be described by the formula as,

I = V/R ( Ampere)

I - Current (Unit is Ampere)

V- Voltage (Unit is volts)

R- Resistance. (Unit is ohm).

Thus, Electric current is the rate of flow of electric charge.

7.36 × 10⁻⁷ Newton is the gravitational force between you and the boulder.

Gravity or gravitational force of the earth is defined as the force on which a planet attracts or pulls another planet towards the center. It is represented by symbol g.

Force is defined as the physical quantity and the vector quantity which acts on an object and causes the object to change its size and shape to stop moving and start moving to decelerate and accelerate. Force has both the directions as well as magnitude. The SI unit of force Newton which is also represented as N, named the scientist Sir Issac Newton.

The Newton's Law of universal gravitational is defined as the universal force of attraction acting between the two bodies which is inversely proportional to the square of the distance between them and the directly proportional to the product of their masses.

It is represented as

[tex]F = \frac{G m_1 m_2}{r^2}[/tex]

Where,

F represents the gravitation force between the two bodies

G represents the gravitation constant

m₁ represents the first body mass

m₂ represents the second body mass

r represents the distance between the two bodies.

Here,

G = 6.67 x 10-¹¹ Nm²/kg

m₁ = 63.7 kg

m₂ = 9,750.6 kg

r = 7.5 m

Now by putting in the above formula we get the gravitational force between you and the boulder.

[tex]F = \frac{6.67 \times 10^{-11}\ Nm^2/kg \times 63.7\ kg \times 9,750.6\ kg}{(7.5 m)^2}[/tex]

[tex]F = \frac{4142825.1774 \times 10^{-11}\ Nm^2/kg}{56.25}[/tex]

   = 7.37 × 10⁻⁷ N

Answer:

A compound has unique properties that are distinct from the properties of its elemental constituents. One familiar chemical compound is water, a liquid that is nonflammable and does not support combustion. It is composed of two elements: hydrogen, an extremely flammable gas, and oxygen, a gas that supports combustion.

According to Newton's First Law of Motion, a body at rest will continue to be at rest unless another force acts on it, and a body moving at a constant speed will continue to move in a straight path unless another force acts on it.

A body must be subject to an external force in order to accelerate (or decelerate) or alter its direction of motion. Net forces or imbalanced forces are other names for external forces.

Inertia is the quality that a body possesses that prevents it from moving when at rest or from speeding up or slowing down while in motion. The mass, or quantity of substance in a body, directly relates to inertia. A body has more inertia the more mass it possesses.

According to the Second Law of Motion, if an imbalanced force applies on a body, the body will accelerate (or decelerate), changing its speed. It is possible to state that a body at rest is thought to have zero speed ( a constant speed). Therefore, an imbalanced force is any force that causes a body to move. Additionally, an imbalanced force is any force that causes a body to move slowly or quickly, such as gravity or friction. The formula below can be used to demonstrate this law.

F= ma

The imbalanced force is F.

The object's mass is m.

The force's acceleration, a, is measured.

The net force is the hypotenuse of the triangle and the value of the net force is 14.14 N.

The net force is the force that has the same effect in magnitude and direction as two  or more forces acting together. We know that force is a vector quantity thus it does have both magnitude and direction.

Since force is a vector, we need to look at the direction of the forces in order to find out what the direction of the net force would have to be. A close look at the image would show us that the net force is the hypotenuse of the triangle.

The value of the net force is;

R = √(10)^2 + (10)^2

R = 14.14 N

Answer:

0.30 m/s²

Explanation:

Given:

v₀ = 0.2 m/s

v = 1.6 m/s

t = 4.7 s

Find: a

a = (v − v₀) / t

a = (1.6 m/s − 0.2 m/s) / 4.7 s

a = 0.30 m/s²

Explanation:

The answer is C because the liquid has to turn into gas which the liquid has volume and a variable shape. Gas does not have volume or shape.

An object has a fixed volume and a variable shape before it changes state. After the change, it can change in both shape and volume then the change of state occurred was liquid to gas

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

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

Liquid has a fixed volume but it can change its shape to any form but gases can change their volume as well as shape, therefore the correct answer is C.

Answer:

h = 20.36[m]

Explanation:

To solve this problem we must calculate the perimeter (length of a circumference) of the circumference, which is denoted by the following equation:

L = 2*π*r

where:

r = radius = 0.9[m]

π = 3.1416

L = 2*(3.1416)*(0.9)

L = 5.654[m]

Now we know that the pulley or circumference had to rotate 3.6 times to get the water out of the well. In this way the depth of the well can be calculated by means of the following equation:

h = 3.6*L

h = 3.6*5.654

h = 20.36[m]
