The answer should be copper. hope this helps :D
-- Whether an object floats or sinks in water depends on whether its density is more or less than the density of water.
-- The density of the rock didn't change when she threw it into the lake.
-- The density of the water didn't change when she threw the rock into the lake.
-- The density of anything never depends on how much of it you have.
-- If the rock sank in two ounces of water, it'll sink in a billion gallons of water.
-- Choose ' <em>A </em>' .
Use F=ma. F is the tension in the cable 7e3N. m is 600kg. Solve for a:
a=7e3/600=11.67m/s^2
Answer:
Tension is also known as Force...
and Force is mass× acceleration.
so....1000×0.70=700N
Answer:
The sports Car can accelerate at 2 m/s².
Explanation:
Force:
Force is the push or pull on an object with mass that causes it to change velocity or to accelerate.
Force represents as a vector, which means it has both magnitude and direction.
Given:
Mass of car = 1500 kg
Force = 3000 Newtons
To Find:
Acceleration, = ?
Solution:
Formula:
Therefore, the sports Car can accelerate at 2 m/s².
