C’est exact!! Excellent travail!

Explanation:

Answer:

The magnitude of the work performed by the mover is 1863 J.

Explanation:

The work can be found using the following equation:

[tex] W = F*d [/tex]

Where:

F: is the force

d: is the displacement = 8.1 m

First, we need to find the net force in the horizontal direction, as follows:

[tex] \Sigma F_{x} = ma = 0 [/tex]

a = 0 since the mover slides a refrigerator at a constant velocity.

[tex] F_{x} = F_{f} = -230 N [/tex]

[tex]F_{f}[/tex]: is the friction force.

Then, the work is:

[tex] W = F*d = -230 N*8.1 m = -1863 J [/tex]    

Therefore, the magnitude of the work performed by the mover is 1863 J.

I hope it helps you!                              

Answer:

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

Explanation:

According to Ohm's law, V = IR

V is the potential difference = 220volts

I is the current = 60 A

R is the resistance (Load)

Calculating the load R

R = V/I

R = 220/60

R = 3.67 ohms

Hence appliance but be connected to a 3.67 ohms load to maintain a safe amount of the current

Answer:

[tex]x = 12.027N[/tex] and [tex]y = 8.964N[/tex]

Explanation:

The first sentence of this question is not explanatory enough. However, I'll assume the force to be 15N

[tex]Force = 15N[/tex]

[tex]\theta = 36.7[/tex] to the horizontal

Required

Solve for the x and y components

Since the given angle is to the horizontal, the x and y coordinates are calculated using the following illustrations.

[tex]Sin\theta = \frac{y}{Force}[/tex] ---- y component

[tex]Cos\theta = \frac{x}{Force}[/tex] ---- x component

Calculating the y component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Sin\theta = \frac{y}{Force}[/tex] becomes

[tex]Sin(36.7) = \frac{y}{15}[/tex]

Make y the subject

[tex]y = 15 * Sin(36.7)[/tex]

[tex]y = 15 * 0.5976[/tex]

[tex]y = 8.964N[/tex]

Calculating the x component.

Substitute 15 for Force and 36.7 for [tex]\theta[/tex]

[tex]Cos\theta = \frac{x}{Force}[/tex] becomes

[tex]Cos(36.7) = \frac{x}{15}[/tex]

Make y the subject

[tex]x = 15 * Cos(36.7)[/tex]

[tex]x = 15 * 0.8018[/tex]

[tex]x = 12.027N[/tex]

Hence, the x and y components of the force are: 8.964N and 12.027N respectively.

Newton’s Three Laws of Motion has a great impact.

Explanation:

Newton’s Three Laws of Motion has a great impact on the bowling game for the 2 students. When the student one throw ball to the student 2, the ball decrease its speed due to the gravity and opposing air. If these forces are removed from the system the ball will continue its motion till another force is applied on it. When the force applied to the ball it produces acceleration in the direction to the applied force. If the ball touches the ground it bounce back with equal force which is a reaction of the ground.

Answer:

I am pretty sure it is A!

The air is warmer near Earth's surface because warm air is denser and sits on top of the Earth's surface. The correct option is B.

The mass of the air per unit volume is known as the air density. Its unit is kg/m³.

Due to the lower pressures in the air above, air expands when it rises. cooling air expands.

The hottest temperatures in the troposphere are often found at the earth's surface because the sun heats the atmosphere predominantly from the surface and because the air cools as it ascends.

Because warm air is denser and lies on top of the surface of the Earth, it is warmer near the surface of the earth.

Hence, the correct option is B.

Answer:

Conduction, convection, and radiation

Explanation:

Conduction is the process in which energy is transferred from a hot body to a cooler body. Convection is a process by which heat is transferred as a result of the movement of heated fluid in the form of air or water. Radiation refers to the transmission of energy through a material medium.

Based on the information provided, a lava lamp could be used to provide an example of conduction, convection, and radiation.

Answer:

For the car to move with constant velocity the additional force required is  [tex]F__{dg} }= -3674 \ N[/tex]

Explanation:

From the question we are told that

  The net force of the car is  [tex]F_{net} = 3674 \ N[/tex]

Generally the total  force acting on the  car is the net force plus the force due to gravity acting in direction of the car (Let denote it as [tex]F__{dg}[/tex])

So the total force acting on the car is mathematically represented as

        [tex]F_{net} + F__{dg}} = F[/tex]

Here this F representing the total force can be mathematically represented as

      [tex]F = ma[/tex]

Now for constant velocity to be attained, the acceleration of the car will be zero  

So  at constant velocity

       [tex]F = m * 0[/tex]

=>    [tex]F = 0 \ N[/tex]

So  

     [tex]F_{net} + F__{dg}} = 0[/tex]

=>   [tex]F__{dg} }= -F_{net}[/tex]

=>   [tex]F__{dg} }= -3674 \ N[/tex]

Let Me Know if I am right   :)

The possible non-SI units to describe the rate of acceleration is the kilometers per hour squared. That is option 4.

Acceleration is the relationship that exists between velocity and time. It is defined as the change of velocity in both speed and direction with respect to time.

The formula for acceleration is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.

Velocity is defined as the rate of objects position with time.

The SI units of velocity = meter/seconds

Substitute for velocity in first equation:

a = meter/sec/sec

a = meter/sec²

But 1000meters = 1 Km

3600 secs = 1 hour

Therefore, the possible non-SI units to describe the rate of acceleration is the kilometers per hour squared.

#SPJ1

Answer:

62.5m

Explanation:

Given parameters:

Mass of the ball  = 0.5kg

Initial velocity  = 35m/s

At the maximum height final velocity is 0m/s

Unknown:

Height of the rise of the ball = ?

Solution:

To solve this problem, we apply the right motion equation which is shown below;

           v²  = u² - 2gh

v is the final velocity

u is the initial velocity

g is the acceleration due to gravity

h is the height

Now insert the parameters and solve;

          0² = 35² - 2(9.8)(h)

      -1225 = -19.6h

           h = 62.5m

The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed,

Explanation:

Newton explained that all objects attract each other, as the Earth is much greater than the apple, it is this that falls towards the Earth.

The moon also falls towards the Earth, but having a tangential speed, the acceleration it has is used in the change of direction of its speed, in general this acceleration is called centripetal

     [tex]a_{c} = g[/tex]

This principle is used in all circular motion devices, for example the merry-go-round in parks, the radius of the circle is proportional to the speed of the turn and therefore to the centripetal acceleration of the device.
