Air pressure is the weight of air on an area. The weight of air
is due to the gravitational forces between the Earth and the
molecules of its atmosphere.
Answer:
Explanation:
n = Order = 1
c = Speed of light =
f = Frequency =
= Angle =
Lattice spacing is given by
The lattice spacing of the crystal is
Gravitational attraction / field strength increases when closer; A light dependent resistor (LDR) can be used as a sensor to detect light intensity.
Answer:
Explanation:
When an amount of energy Q is supplied to a substance of mass m, the temperature of the substance increases by , according to the equation
where is the specific heat capacity of the substance.
In this problem, we have:
is the amount of heat supplied to the sample of gold
m = 0.1 kg = 100 g is the mass of the sample
is the specific heat capacity of gold
Solving for , we find the change in temperature
And since the final temperature was
The initial temperature was
Answer:
d: ice is less dense than liquid water.
Explanation:
hope this helps! ( brainliest would be appreciated :)
