Assuming that the magnitude is additive, then you simply have to add the brightness four times. This is because each star has 2 magnitudes of 8.34. As a result, you have to add 4 magnitudes of 8.34. The solution is as follows:
Magnitude = 4(8.34)
Magnitude = 33.36
Answer:
The answer to the question is
Momentum
Explanation:
Momentum in physics refer to the attribute that a body has by virtue of its mass and velocity. It is found by multiplying the mass of the moving object and the velocity, hence
Momentum = Mass × Velocity = m·v
Newton first law of motion states that the force acting on an object is proportional to the rate of change of momentum produced
Therefore when we find the momentum of the two cars, the one that has the greater momentum will require the most force to stop it.
Momentum is a physics term; it refers to the quantity of motion that an object has. A sports team that is on the move has the momentum. If an object is in motion (on the move) then it has momentum
Momentum
To thaw a product requires it to undergo the process of
being subjected to latent heat of fusion. In this process, there is no change
in temperature however there is a change of phase from solid to liquid. What is
being thawed here actually is the frozen ice into liquid water which is in the
vegetables.
From the references, the latent heat of fusion of water
is:
Δ H = 333.55 kJ / kg
Therefore the amount of heat required to thaw the frozen
vegetable is:
Heat required = Δ H * m
Heat required = (333.55 kJ / kg) (0.450 kg)
Heat required = 150.10 kJ
In 1 kcal there is 4.184 kJ, therefore:
Heat required = 150.10 kJ (1 kcal / 4.184 kJ)
<span>Heat required = 35.87 kcal</span>
Answer:
534.7
Explanation:
55/1010 = 0.0545m^3
1000(0.0545)(9.81) = 534.7 N (kept at 4 sig figs)
