## Brainiest if you answered with the solution! 1.A bus travels

1.A bus travels at 54km/h while moving but after accounting for stopping time, to let passengers on and off the coach, it averages a
speed of 45km/h. How many minutes does the bus stop for each hour?
2.The distance between the two stations is 540 km. A train takes 3 hours to
cover this distance. Calculate the speed of the train in km/hr and m/s.
Thank you…

1. Distance/Speed = Time

9km/54kmph = 0.16 hours

0.16 x 60 = 10 minutes

2. — km/hr : 540 ÷ 3 = 180 km/hr

— m/s :540 km = 540000m

3 hr = 10800

## Solve the following, show your solution1. A cart rolls down

1. A cart rolls down a ramp. The cart has a mass of 0.5 kg. Using a spring scale, you measure a net force of 2 newtons pulling the car down. Calculate the acceleration of the cart.

2.An airplane needs to accelerate at 5 m/sec2 to reach

take-off speed before reaching the end of the runway. The mass of the airplane is 5,000
kilograms. How much force is needed from the

engine?

## Problem 1:

F = 2 N

m = 0.5 kg

a

### Equation:

[tex]a = dfrac{F}{m}[/tex]

### Solution:

[tex]a = dfrac{text{2 N}}{text{0.5 kg}}[/tex]

a = 4 m/s²

———————————————————

## Problem 2:

m = 5,000 kg

a = 5 m/s²

F

F = ma

### Solution:

F = (5,000 kg)(5 m/s²)

F = 25,000 N

## urning Objectives: 1. Explain how heat is converted into work

Ask: urning Objectives: 1. Explain how heat is converted into work within a system. 2. Describe how heat and work can change the internal energy of a system. 3. Calculate the change in internal energy of a system given the heat added to or off by the system and work done on or by the system 4. Construct a model or draw a diagram that demonstrate that heat can do work

sorry dko alm sagot✋

Explanation:

hi

1.)The Hot Resevoir – heat energy is created by some process such as combustion of a fuel to provide the heat energy. The working body – converts the heat energy into work. In real heat engines, the conversion process is never 100% efficient, so the work output is always less than the heat energy supplied.

2.)The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics is ΔU = Q − W

3.)The first law of thermodynamics states that the change in internal energy (ΔU) of a closed system is equal to the heat added to the system (Q) minus the work done by the system (W).

ΔU = Q – W

So if the internal energy decreases, we can conclude that the quantity (Q – W) is negative, therefore the W > Q meaning the system did more work (perhaps by displacing its environment in the form of PdV work), than the amount of heat that may have been added to the system.

If it was known that the system is in an insulated chamber, then no heat could be transferred along its boundary and we could determine that the system did positive work on its environment by expanding its volume (W = PdV).

If it was known that the system was kept at a constant volume, then no displacement work could be done and the only way the system could experience a decrease in internal energy would be for it to lose heat.

However, neither work done, nor heat added are exact differentials, and therefore both depend on the path taken through which the system transitioned from one state to another.

## A calculator falls off the side of the student's table

Ask: A calculator falls off the side of the student’s table and hits the floor 0.3s later.
1) How high is the table?

2) How fast is the calculator travelling when it hits the floor?

Using Projectile Motion:

it has has a gravitational acceleration which is -9.8m/s^2

It is a table so it might a cm lengths

V=Vi+at

V=0+(980cm/s^2)(0.3s)

V=294cm/sd=0.5[Vi+Vf]t

d=0.5[0+294cm/s]0.3

d=44.1cm

## A lighthouse beacon is 140m above sea level. The waters

Ask: A lighthouse beacon is 140m above sea level. The waters around it abound in rocks as far as 100m from the base of the lighthouse. an observer on the dect of a ship 7m above sea level finds that the angle of elevation of the beacon is 30 degrees. how many meters is the ship clear off from the rocks?

we can’t use calculator, so we can only rely on circular function :((

If you could create a proper diagram of this question, you could actually answer this without using a calculator.

If the angle is 30 degrees, just remember the values of the unit circle with respect to angles in radians.

30 degrees is equivalent to π/6

sin(π/6)=1/2
cos(π/6)=(√3)/2
tanx=sinx/cosx

Hope that helps.
