True as the independent variable is over the dependent variable and controls it as the dependent relies on the independent.
Answer:
Trish
Explanation:
the work done by each girl in throwing the ball is equal to the kinetic energy acquired by the ball. The ball thrown by Jamie has for sure more kinetic energy than the ball thrown by Trish, since it travels for a longer distance (25 m against 15 m), therefore this means that Jamie did more work than Trish in throwing the ball.
Answer:
1)the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That's very cold, and there's no way liquid water could exist.
2)Neptune has the wildest and strangest weather in the entire Solar System. It has huge storms with extremely high winds. Its atmosphere has dark spots which come and go, and bright cirrus-like clouds which change rapidly. Neptune has an average temperature of -353 Fahrenheit (-214 Celsius).
3)To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit,
Answer:
Radius of aluminium sphere which has same mass as of sphere of iron with radius 14 m is 40.745 meters.
Explanation:
Let the radius of aluminium sphere be
From the relation between density, mass and volume we know that
Applying equation 'i' separately to iron and aluminium sphere we get
Equating the masses of iron and aluminium spheres we get
4) 55m
5) 30 seconds
6) 1.83m/s
