In order to give the apple more kinetic energy than it has right now,
you must make it move faster than it is moving right now. You could
drop it, roll it, toss it, or gingerly place it in a moving car or airplane.
Whatever method you select, motion ... specifically speed ... is the
key to kinetic energy.
Symbols such as cross motivates me to go to church.
Answer:
6 beats
If one fork beats once and another twice in the same time period
you would hear 1 beat. (Same for 2 and 3 beats).
Answer:
The mass of the ball is 0.23 kg
Explanation:
Given that
radius ,r= 3.74 cm
Density of the milk ,ρ = 1.04 g/cm³ = 1.04 x 10⁻³ kg/cm³
Normal force ,N= 9.03 x 10⁻² N
The volume of the ball V
![V=\dfrac{4}{3}\pi r^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Cpi%20r%5E3)
![V=\dfrac{4}{3}\times \pi \times 3.74^3\ cm^3](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B4%7D%7B3%7D%5Ctimes%20%5Cpi%20%5Ctimes%203.74%5E3%5C%20cm%5E3)
V= 219.13 cm³
The bouncy force on the ball = Fb
Fb = ρ V g
Fb + N = m g
m=Mass of the ball = Density x volume
m = γ V , γ =Density of the Ball
ρ V g + N = γ V g ( take g= 10 m/s²)
![\gamma =\dfrac{N+\rho V g}{V g}](https://tex.z-dn.net/?f=%5Cgamma%20%3D%5Cdfrac%7BN%2B%5Crho%20V%20g%7D%7BV%20g%7D)
![\gamma =\dfrac{9.03\times 10^{-2}+1.04\times 10^{-3}\times 219.13\times 10}{219.13\times 10}](https://tex.z-dn.net/?f=%5Cgamma%20%3D%5Cdfrac%7B9.03%5Ctimes%2010%5E%7B-2%7D%2B1.04%5Ctimes%2010%5E%7B-3%7D%5Ctimes%20219.13%5Ctimes%20%2010%7D%7B219.13%5Ctimes%2010%7D)
γ = 0.00108 kg/cm³
m = γ V
m = 0.00108 x 219.13
m= 0.23 kg
The mass of the ball is 0.23 kg
Answer:
Explanation:
The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. ... Mesosphere: As the altitude increases, the air temperature decreases. The Mesosphere, like the troposphere layer, has a decrease in temperature with altitude because of the decreases in the density of the air molecules.
