Explanation:
In a weightless environment a force of 5 Newtons is applied horizontally to the right on a rock with a mass of 1 kg and to a pebble with a mass of 0.1 kg.
Take into account that conduction is the process at which heat is propagated by the termical motion of the molecules, without a real desplacement of the molecules.
Based on the previous definition, the following is an example of heat transfer by condu
Answer:
11.5 m
Explanation:
First, find the time it takes to land.
Given:
Δy = -1.5 m
v₀ = 10 sin 37° m/s
a = -9.8 m/s²
Find: t
Δy = v₀ t + ½ at²
-1.5 m = (10 sin 37° m/s) t + ½ (-9.8 m/s²) t²
-1.5 = 6.02 t − 4.9 t²
4.9 t² − 6.02 t − 1.5 = 0
Solve with quadratic formula:
t = [ -(-6.02) ± √((-6.02)² − 4(4.9)(-1.5)) ] / 2(4.9)
t = 1.44
Now find how far it moves horizontally in that time:
Given:
t = 1.44 s
v₀ = 10 cos 37° m/s
a = 0 m/s²
Find: Δx
Δx = v₀ t + ½ at²
Δx = (10 cos 37° m/s) (1.44 s) + ½ (0 m/s²) (1.44 s)²
Δx = 11.5 m
The cat lands 11.5 meters from the table.
well if this helps you I do not know what "h and n" is but I do know that
friction produces heat
