Help me pls there’s 25points for you “A ball is projected vertically upwards with a velocity 30m/s. After what time
it is 40 m high from the point of projection? Take g 10 m/s.”

explanation:

could i give you a exaplo that could you?

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
