Answer:
Density = Mass / Volume
Mass = .3 kg
Volume = 2 * 5 * 4 = 40 m^3
Density = .3 g / 40 m^3 = .0075 kg / m^3
1 kg/m^3 = kg * 1000 g / kg / (1 m^3 * (100 cm/m)^3) = 10E-3 gm/cm^3
Density = 7.5 E-3 gm/cm^3
According to Newton’s second law acceleration= force/mass
So acceleration = 10/2
= 5m/s^2
Answer:
Every object located in the universe emits radiation.
Explanation:
This is the fact which represents evidence of The Big Bang Theory.
Answer:
3.48 seconds
Explanation:
At maximum height Vf=0 m/s
Vf= Vi - g*t
⇒g*t= Vi
⇒t= Vi/g
⇒t= 112/32.17 sec
⇒ t= 3.48 s
so the projectile will achieve its maximum height in 3.48 seconds.
