The volume occupied by three milliliters of water is the same as three cubic centimeters of water
Answers
The volume occupied by three milliliters of water is the same as three cubic centimeters of water is true. The conversion is as follows.
3mL (1 L/1000 mL) (1 m3/1000 L) (100 cm/1 m)^3 = 3 cm3

Impulse = (force) x (length of time the force lasts)
I see where you doodled (60)(40) over on the side, and you'll be delighted
to know that you're on the right track !
Here's the mind-blower, which I'll bet you never thought of:
On a force-time graph, impulse (also change in momentum)
is just the area that's added under the graph during some time !
From zero to 60, the impulse is just the area of that right triangle
under the graph. The base of the triangle is 60 seconds. The
height of the triangle is 40N . The area of the triangle is not
the whole (base x height), but only 1/2 (base x height).
1/2 (base x height) = 1/2 (60s x 40N) = 1,200 newton-seconds
That's the impulse during the first 60 seconds. It's also the change in
the car's momentum during the first 60 seconds.
Momentum = (mass) x (speed)
If the car wasn't moving at all when the graph began, then its momentum is 1,200 newton-sec after 60 seconds. Through the convenience of the SI system of units, 1,200 newton-sec is exactly the same thing as 1,200 kg-m/s . The car's mass is 3 kg, so after 60 sec, you can write
Momentum = M x V = (3 kg) x (speed) = 1,200 kg-m/s
and the car's speed falls right out of that.
From 60to 120 sec, the change in momentum is the added area of that
extra right triangle on top ... it's 60sec wide and only 20N high. Calculate
its area, that's the additional impulse in the 2nd minute, which is also the
increase in momentum, and that'll give you the change in speed.

Ohm's law :
V = IR
The amount of work done is
P = IV or P = I^2R (using Ohm's law to substitute)
Therefore,
P = 64*15
= 960W
So the total energy released is
Pt = 960*60
= 57600J
What is ohm's law ?
"Ohm's law states the relationship between electric current and potential difference. It states that the current that flows through most conductors is directly proportional to the voltage applied to it."
The strength of a direct current is directly proportional to the potential difference and inversely proportional to the resistance of the circuit.
What is work done?
Work done : W = (|F| cosθ) |d|
"Work done is defined as the multiplication of magnitude of displacement d and the component of the force that is in the direction of displacement."

Answer:
Distance traveled will be
Explanation:
We have given speed of the light
We have to find the distance traveled by light in 1 year
We know that 1 year = 8760 hour
And 1 hour = 60×60 = 3600 sec
So 1 year
We know that distance = speed × time
So distance traveled by light in one year
We have to fond the distance in km
As we know that 1 km = 1000 m
So
Final answer:
Radio messages will travel approximately 9.46 x 10^12 kilometers in exactly one year.
Explanation:
Radio waves travel at the speed of light which is approximately 3.00 x 108 m/s.
To find out how many kilometers radio messages will travel in exactly one year, we need to first convert the speed of light into kilometers per second.
Since there are 1000 meters in a kilometer, we divide the speed of light by 1000 to convert from meters to kilometers. Then, we multiply this value by the number of seconds in a year (365 days x 24 hours x 60 minutes x 60 seconds) to get the total distance traveled in kilometers.
In summary, radio messages will travel approximately 9.46 x 1012 kilometers in exactly one year.
