if a cat is running at a constant speed of 10km/h for 5 s, what is its average speed and what is its instantaneous speed at 4 s?
Answers
Here a cat is running at constant speed which is given as 10 km/h for 5s
So here the average speed is defined as total distance moved in total time interval
so here it is given by
since
here speed of cat is constant so it will remain the same
And hence the average speed and instantaneous speed at any instant for this duration will remain the same
so here answer would be
average speed = 10 km/h
instantaneous speed = 10 km/h

AI-generated answer
A hypothesis is a statement that predicts what will be observed in an investigation. It is based on background research performed by the scientist and is usually written in an if-then format that describes the proposed relationship between variables. Therefore, all of the statements listed are true about hypotheses.

The gravitational forces are the same. (C).
1 kg is 1 kg. It always has the same weight, no matter whether it's made of kryptonite, concrete, or chicken soup.

Answer:
The earth rotates because of the way it was formed. Our Solar System formed about 4.6 billion years ago when a huge cloud of gas and dust started to collapse under its own gravity. As the cloud collapsed, it started to spin.

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.
