The base unit for time is Second.
Answer:
A satellite goes into orbit by getting a ride with a rocket or the Space Shuttle. Gravitational pull and the velocity of the satellite help it remain in orbit.
Explanation:
Answer:
10 mph
Explanation:
- Exceeding speed limit is one of the major causes of road accident.
- Crash severity increases with the speed of the vehicle at impact.
- The probability of death, disfigurement, or debilitating injury grows with higher speed at impact.
The above consequences double for every 10 mph over
50 mph that a vehicle travels.
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
