The derivative of
h(t) = (-g/2)t² +v0·t + h0
is
h'(t) = -gt +v0
This is zero at the maximum height, so the time can be found as
0 = -gt +v0
gt = v0
t = v0/g
When warm currents move over cool land surface, they dissipate heat due to
the temperature gradient . They hence warm up the land they blow over. If a
cold current blows over warm land, the land loses heat to the current. This is
how currents distribute heat across the earth.
When the current blow from water to land, the current will be warm or cold
depending on the water temperatures. Therefore, they will warm up or cool the adjacent
land mass.
Answer:True
Explanation:Because the deflection in galvanometer is calculated by the following formula;
Answer:
The force is -1620.73 N.
Explanation:
Given that,
Mass of car = 1000 kg
Velocity = 1 m/s
Distance = 2 m
Angle = 30°
We need to calculate the force
Using formula of work done





Put the value into the formula


Hence, The force is -1620.73 N.
Answer: The color of candy cane
Explanation:
An independent variable is the Variable that the scientist changed in order to change the dependent variable. The scientist changes the color of the candy cane to test the rate at which they dissolve.
