Answer:

for any object in motion , distance is always greater than displacement

For any object in motion, distance is always greater or equal to the displacement but it can never be less than the displacement because displacement is the shortest distance measured between the initial and the final position.

An object's position changes if it moves in relation to a reference frame, such as when a passenger moves to the back of an airplane or a professor moves to the right in relation to a whiteboard.

Displacement describes this shift in location.

Distance is always higher or equal to displacement for any item in motion, but it can never be less because displacement is the shortest distance between the beginning and end positions.

Answer:

3. Power is the amount of work done in a certain period of time. 

Explanation:

==>  The total mass resting on the table is (5 kg + 3 kg) = 8 kg.

==>  The total weight of that mass is (8 kg) x (9.8 m/s) = 78.4 newtons

==>  The boxes are stacked.  So the table doesn't know if the weight on it is coming from one box, 2 boxes, 3 boxes, or 100 boxes in a stack.  The table only knows that there is a downward force of 78.4 newtons on it.

==>  The table stands in a Physics classroom, and it soaks up everything it hears there.  It knows that every action produces an equal and opposite reaction, and that forces always occur in pairs.  

Ever since the day it was only a pile of lumber out behind the hardware store in the rain, the table has known that in order to maintain the good  reputation of tables all over the world, it must resist the weight of anything placed upon it with an identical upward force.  This is the normal thing for all good tables to do, up to the ultimate structural limit of their materials and construction, and it is known as the "normal force".

So the table in your question provides a normal force of 78.4 newtons. (d)

Answer:

It means that 400 J of heat is the required amount to raise or lower thh temperature of a 1kg piece of copper

Explanation:

390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C

From the given information,

The specific heat capacity of copper is 390 J/Kg °C. To determine what this means, we will define the term specific heat capacity.

The specific heat capacity of a substance is the amount of energy required to raise the temperature of 1 kg of the substance by 1 °C.

Therefore, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

Hence, 390 J/Kg °C specific heat capacity of copper means, 390 J of energy is required to raise the temperature of 1 kg of copper by 1 °C.

Answer:

0.99932188871837 rounded to 2 significant figures is 1.00m or 1.0m

Explanation:

Step 1 - First calculate the force with the formula: Force = mass ×  acceleration due to gravity/ (F=mg) {g= 9.8m/s²}

4.0kg × 9.8m/s² = 39.2 Newtons

Step 2 - Then calculate the Kinectic power with the following procedure:

Kinectic force = the coefficient of Kf × mg

0.50μ × 39.2 N = 19.6 Newtons of Kinectic force

Step 3 - Use the equation for Work that is = F×d; use the value of Kf and multiply it by the given distance

W = 19.6 N × 2.0m = 39.2 Joules of energy

↓Remember that the product of Work is Energy (W=E) and that in some cases, we can set W as = kinetic energy ( [tex]\frac{1}{2}[/tex]mass×velocity²) or as = gravitational potential energy (mass *acceleration due to gravity*height)

↑Since the unknown variable that we are told to find is 'height', let's use the second formula to help us solve the problem, where we said that GPE = mgh / PEg = mgh

Step 4 - Find the missing height using the formula, Energy gained from (W = mgh), by rewriting (mgh) to solve for h

39.2 J of E = 4.0kg × (9.8 m/s² × h)

h = [tex]\frac{PEg}{mg}[/tex]

h = [tex]\frac{39.2N}{9.8m/s{2} times 4.0kg}[/tex]  

Height of box on-ramp = 1.0m

Answer:

E = 98 J

Explanation:

Given that,

The mass of a ball, m = 1 kg

It is being suspended 10m above the ground & is then dropped.

We need to find the ball's kinetic energy just before it hits that ground. The conservation of energy holds here. It means, the kinetic energy just before it hits that ground is equal to its potential energy i.e.

[tex]E=mgh\\\\E=1\times 10\times 9.8\\\\E=98\ J[/tex]

so, the required energy is 98 J. Hence, the correct option is (b) "98 J".

========================================

Work Shown:

To find the momentum, we multiply the mass and the velocity.

m = mass = 1500 kg

v = velocity = 3 m/s

p = momentum

p = m*v

p = (1500 kg)*(3 m/s)

p = (1500*3) kg m/s

p = 4500 kg m/s

The momentum of an object is the product of its mass and velocity. Thus momentum of the car with 1500 kg and velocity of 3 m/s is 4500  kg m/s.

Momentum is a physical quantity that measure the ability to keep the force which make an object moves faster. Momentum like force is a vector quantity and is characterized with magnitude and direction.

Momentum is the product of velocity and its mass. Hence as the mass or velocity increases, momentum also increases. Increase in momentum makes the object moves faster.

Given mass of car = 1500 Kg

velocity = 3 m/s

momentum = velocity × mass

= 1500 Kg × 3 m/s

= 4500 Kg m/s.

Therefore, the momentum of the car is 4500 kg m/s.
