No.1 answer

if there is no friction in a simple machine, work output and work input are found to be equal in the machine.

No.3 answer

machine that is 75% efficient means that 75% of the work input is obtained as the useful output and the remaining 25% has been lost in overcoming the friction.

No.4 Answer

Option A is correct. The resultant quantity is 50m/s to the right.

Vector quantities are quantities that have both magnitude and direction.

From the diagram shown,  we can see that 100m/s vector moves in the positive x-direction, this means that the  of magnitude the vector is +100m/s.

For the vector 50m/s, we can see that it is moving in the negative x-direction, this shows that the magnitude of the 50m/s vector is -50m/s.

Resultant speed = +100 - 50

Resultant speed = +50m/s

Since the resultant speed is a positive value, this mean that the resultant quantity will be moving towards the right.

Hence the correct option will be 50m/s to the right.

We have that for the question, Does a cat’s heart rate change while it is napping?

Cats heart rate do not increase while napping.

The range of heart beat of a cat is 140 and 220 bpm

From the Question we are asked

Does a cat’s heart rate change while it is napping.

The answer is NO

Cats heart rate do not increase while napping. Cat have a normal heart beat maximum of 220 beats per minute consistently.The range of heart beat of a cat is 140 and 220 bpm

Therefore

There is something with a cat with heart rate above this number.

Answer:

W = F × d

W = 1 × 1

W = 1 Joule

step by step explanation

An apple is having a force of 1 N and it travels to a distance of 1 m then the work done on the apple by the force of gravity will be equal to 1 J.

Work is a physics term used to describe the transfer of energy that occurs when an object changes above a distance because of an external force, at least some of which is given in the vector of the dislocation. The element of the strong acting all along the path multiplied by the length of the path can be used to calculate work if the force is constant.

Mathematically, this idea is expressed as W = fd, where W is the effort and f is the force multiplied by d, the distance. Work is completed whenever the pressure is applied at an angle with regard to displacement.

As per the given information in the question,

Force, f = 1 N

Distance, d = 1 m

Then, the work done will be,

W = fd

W = 1 × 1

W = 1 J.

Explanation:

Givens

vi = 50 m/s

vf = 0

a = - 9.81

t = ?

Formula

t = (vf - vi)/a

Solution

t = (0 - 50)/-9.81

t = 5.097

Notice that a is made into a minus. It does not mean subtract. It means that the direction of the projectile and gravity must go in opposite directions. You will find that direction is a critically important consideration in physics.

Answer:

It'd take it 5.10 seconds

Explanation:

At the top of the launch, it is maximum height, h

formular derivation :

At maximum height, final velocity, v is zero

From first newtons equation:

[tex]{ \sf{v = u + gt}}[/tex]

v is the final velocity

u is the initial velocity

g is acceleration due to gravity

t is the time taken

but v is zero:

[tex]0 = u + gt \\ gt = u \\ t = \frac{u}{g} [/tex]

since it is vertical motion, u = usin(theta), where angle is 90°

[tex]{ \boxed{t = \frac{u \sin( \theta) }{g} }}[/tex]

t is the time taken to reach the top of the launch:

substitute, taking g to be 9.8 m/s²

[tex]t = \frac{50 \times \sin(90 \degree) }{9.8} = \frac{50}{9.8} \\ \\ { \boxed{ \boxed{time = 5.10 \: seconds}}}[/tex]

Answer: As the temperature increases, the flow time increases.

Explanation: i took the test

The relationship between the variables on this graph is that As the temperature increases, the flow time increases, therefore the correct answer is option B.

It is a scale of temperature used to measure the temperature, the kelvin scale of temperature is also known as the absolute scale of temperature.

The Standard International unit of thermodynamic temperature is the kelvin, often known less frequently as the degree Kelvin. The formal definition of one kelvin is 1/273.16  of the thermodynamic temperature of pure water's triple point.

As shown in the graph as the temperature increase across the X axis the flow time is increasing as well, these two variables are directly proportional to each other.

Thus, The graph shows a link between the variables, showing that when the temperature rises, flow time also rises, hence option B is the proper response.
