Answer:
3kg
Explanation:
impulse = MV
then
m1v1=m2v2
when the values are subtitude
then
m2=1.2*25/10
m2=<em>3</em><em>0</em><em>k</em><em>g</em><em>/</em><em>/</em>
Answer: Gas
Explanation:
Matter exists in three different phases, they are:
- Solid
the phase of matter with fixed shape, high density and non-moving particles that are held together by strong bonds. Example of solids are stone and chalk
- Liquid
the phase of matter with loosely held particles that are held together and take up the shape of the containing vessel. Examples of liquid are water, orange juice
- Gas
This is the phase of matter with no fixed shape or volume, rather its molecules travel rapidly and randomly within the containing vessel. Examples of gases are ammonia and oxygen
Thus, the phase of matter with no fixed shape or volume is known as gas
The gravitational pull of Earth is stronger in satellite A
Answer:
d
Explanation:
This is because momentum is defined as p = mv
delta p = Force *time
neither velocity nor time is given so a conclusion cannot be made on which has the greatest momentum change.
Since it is restricted at both ends, λ/2 = length of string
λ/2 = 1.5m
λ = 1.5*2 = 3m
