The ice and how the blades are made
Blood
I learned this in anatomy, and I've taken it twice
In my own words, I would say that physics is an area of science that seeks to explain and understand the fundamental nature of the dynamics of objects, essentially defining how objects can interact, in space and in time.
Answer:
Procyon appears brighter in the sky
Explanation:
Apparent magnitude of star Antares = 1.0
Apparent magnitude of star Procyon = 0.4
Pogson's Ratio
m₂-m₁ = -2.50 log(B₂/B₁)
where, m is the apparent magnitude
B = Brightness of star or flux coming towards us (W/m²)
∴Larger magnitudes correspond to fainter stars so here 1>0.4 which means Antares appears dimmer and Procyon appears brighter.
<span>the body is moving horizontally, it doesnt matter watever kind of horizontal forces are acting.
Therefore the normal force is equal to the weight
N=mg=4.2*9.8=41N
Note: the other data in the problem have no relevance
answer
</span> the normal force on the sled is 41N
