A car accelerates at a rate of 3.0 m/s^2. If it’s initial speed is 8.0 m/s, how many seconds will it take the car to reach a final speed of 25.0 m/s? Please show work

Answers

vf= 25 m/s
vi= 8 m/s
a= 3.0 m/s^2
t=?
You can substitute these values into the big five kinematic equations.

vf=vi+at
25= 8+3t
3t=17
t=5.67 seconds

if you use the compound pulley, you will need to pull twice the distance but with less force. the force you need is equal to one half the weight of the box plus 25 N. what is the force needed?

Answers

Answer:

F= 25/2 = 12.5N

Explanation:

When you use a compound pulley the force required depends on the mechanical advantage of the compound pulley. This is known as rate of loss of distance or the ratio of the force to the load.

M.A = Effort distance /Load distance. OR M.A = Load/Effort

Convert an absolute pressure of 6.31 ✕ 105 N/m2 to gauge pressure in lb/in2

Answers

Answer:

The gauge pressure is = 91.52 lb/in²

Explanation:

Given data,

The value of pressure in S.I unit, = 6.31 x 10⁵ N/m²

The conversion formula for SI unit into US Customary Units is given by,

1 N/m² = 1.45 x 10⁻⁴ lb/in²

Using the conversion formula, the new value of pressure becomes,

Pressure = 6.31 x 10⁵ X 1.45 x 10⁻⁴ lb/in²

= 91.52 lb/in²

Hence, the gauge pressure is, ς = 91.52 lb/in²

In the national grid,what does the step up transformer do?

Answers

In the National Grid, the Step Up Transformer increases the amount of voltage that is passing through the grid at any one time. These are used at power stations, as without them, there would not be enough power to transport the electricity around the national grid.
Hope this helps :)

The power that's lost when current flows through anything is

(current)² times (resistance).

You can see that in order to minimize the power lost in transporting electrical
energy from one place to another, you'd want to make both the resistance of
the conductors and the current through the lines as low as possible.

The resistance is reduced by using heavier (fatter) conductors, and using
as much silver or copper in them as possible ... both very expensive.

Power = (current) times (voltage), so the way to reduce the current while
shipping the same power from place to place is to increase the voltage.
That's exactly what the transformer does ... it changes the voltage and
current, while keeping their product the same. It's used to step the voltage
up for transmission, in several steps from the generating station all the way
to the residential neighborhood, and then finally back down, on the pole
near your house.

The balance between incoming solar energy and out going energy radiated into space is called...

Answers

Based on the physics principle of conservation of energy, this radiation budget represents the accounting of the balance between incoming radiation, which is almost entirely solar radiation, and outgoing radiation, which is partly reflected solar radiation and partly radiation emitted from the Earth system, including the atmosphere.

Help me what times would it e and where do i put a x to show where London will be in 12 hours time

Answers

Look at the picture I attached. It's a part of your sheet,
with some added information.

-- The line between the day-side and night-side of the Earth is the line
where day changes to night, or night changes to day. Even if we don't know
which way the Earth is turning in the picture, London is halfway between
sunrise and sunset, so it's about Midnight there.

-- Do you remember that the Earth spins all the way around in 24 hours,
and half-way around in 12 hours ?
So in 12 hours from now, London will be halfway around, on the day side,
and it will be about Noon there,

When you see where I placed London at Noon on my drawing, you may
wonder why it's so 'high up' on that side.

Remember that the Earth is not spinning arounf the sunrise/sunset line.
It's spinning around the 'axis' ... the line through the north and south poles.

This is a picture of the Earth during the dead of Winter in the northern hemisphere.
The north pole is tipped away from the sun. You can see that London spends
much more than half of each spin in the dark, and much less than half of it in
the light. This corresponds to the short days and long nights of Winter.
