Answer:
m = 1
Explanation:
K.E = 8J
v = 4m/s
m = ?
Now,
K.E = 1÷2mv^2
8 = 1÷2 × m × (4)^2
8 = 1÷2 × m × 16
8 = m × 8
m × 8 = 8
m = 8 ÷ 8 = 1
m = 1

K.E. = 1÷2mv^2
K.E = 1÷2 × 1 × 4^2
K.E. = 8J

Answer:
This is because of Van der Waals forces
Explanation:
The ideal gas laws do not take into account the inter molecular forces that exist between the molecules of the gas. However, Van der Waals discovery showed that some weak forces of attraction exist between the molecules of the gas and at high pressures, their presence can affect the volume of the gas, making it larger than what is predicted by the ideal gas law.
These forces of attraction between the gas molecules is called Van der Waals forces.
Answer:
The outer surface of bone is called the periosteum (say: pare-ee-OSS-tee-um). It's a thin, dense membrane that contains nerves and blood vessels that nourish the bone. The next layer is made up of compact bone. This part is smooth and very hard.
