Answer:
Normal force=mg
Explanation:
The reaction force of weight is the normal force.
in order to find the normal for we need to write all the forces and set it equal to the net force:
N-mg=ma (since it is a constant speed the a=0)
N=mg
Answer:
true
Explanation:
takes time for most plates to move but throughout time they keep moving just at a slow pace
Explanation:
PRIMERO HACES EL RECUENTO DEL TIEMPO Y LO CONVIERTES EN
SEGUNDOS Y ENTONCES
<em>t</em> = 227 s 
= 227 S - 38 s = 189 s
= 38 s
LUEGO USANDO LA ECUACIÓN DE GALILEO GALILEI SSUPONIENDO
QUE EL MOVIL VIAJA A VELOCIDAD CONSTANTE
<em>v</em> = 3.50 m/189 s = 0.0185 m/s
PARA LA DISTANCIA NTRE B Y C
= 0.0185 m/S( 38 s) = 0.703 m
LA HORA EN QUE EL MOVIL PASA POR A ES
11:43:15 - 38 s - 189 s = 11:39:29
Answer:
The male skater's velocity is 13.71 m/s.
Explanation:
From the law of conservation of momentum:
m1u1 = (m1 + m2)u2
m1 is the mass of the male skater = 78.2 kg
m2 is the mass of the female skater = 48.5 kg
u1 is the velocity of the male skater as a result of the push
u2 is the velocity with which the male skater pushed away the female skater = 8.46 m/s
u1 = [(78.2+48.5)8.46] ÷ 78.2 = 1071.882 ÷ 78.2 = 13.71 m/s
Answer: The given statement is True.
The proliferation of photosynthetic planktons results in harmful algal blooms. Due to this, the surface of the water body gets completely covered with algal bloom. This blocks the sunlight as it can not penetrate the water. Due to this, photosynthetic planktons are no more able to perform photosynthesis. This ultimately ends up depleting all oxygen from the body of water.
Thus, the given statement is true.
