Answer:
103.5m/5.5s= 18.8m/s
Explanation:
Formula for finding velocity average is:
v average= change in x(meters)/ change in time(seconds).
Answer: 45000kgm/s
Explanation:
Given that:
Mass of speed boat = 1500 kg
Velocity of speedboat = 30 m/s
Speed boats Momentum = ?
The Speed boat momentum is the product of its mass and the velocity by which it moves. Momentum is a vector quantity and measured in kgm/s
i.e Momentum = mass x velocity
= 1500 kg x 30 m/s
= 45000kgm/s
Thus, the speed boats momentum is 45000kgm/s
Answer:
this is in the middle of the wheel and helps it rotate it is an axle
Coefficient of volume expansion is 8.1 ×10⁻⁴ C⁻¹.
<u>Explanation:</u>
The volume expansion of a liquid is given by ΔV,
ΔV = α V₀ ΔT
ΔT = change in temperature = 48.5° C
α = coefficient of volume expansion =?
V₀ = initial volume = 2.35 m³
We need to find α , by plugin the given values in the equation and by rearranging the equation as,
= 8.1 ×10⁻⁴ C⁻¹.
The global warming is because of the car pollution was the fire in the forest it makes the air one and the warm air grocery Pacific side which makes me glacier it mostly glacier and breaks down two bases and the rising of the water makes the global warming too much so people are trying to use this card and try to use cycles because of global warming .
