Need help with the explanation part of this question A group of friends go sliding down a water slide seperately, they sit on a sled and go down the slide.
The decrease in gravitational potential energy of one rider on the slide was7.66kJ, the rider moved through a verticle height of 16.0M with a gravitational field of 9.8 N/Kg

at the bottom of the slide, all the friends and their sleds have approximately the same speed. why? (4 Marks)

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
