A television of mass 13 kg sits on a shelf. What is the normal force acting on the television?
2 answers:
Answer:
Normal force, F = 127 N
Explanation:
It is given that,
Mass of the television, m = 13 kg
It is sitting on the shelf. We have to find the normal force acting on it. The forces acting on it are normal force and its weight. So, the normal force is given by :
F = mg
g = acceleration due to gravity
F = 127.4 Newton
or
F = 127 N
Hence, the normal force acting on the television is 127 N

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
