The net force acting on the child is 200N.
When two or more forces are acting on the system of objects, then the to attain equilibrium, net force must be zero.
The net force acting on the child will be
Net force = Sum of all the individual force with sign
Net force = -100 + 0 + 100 +200
Net force = 200 N.
Therefore, the net force acting on the child is 200 N.

Answer:
Congress
Explanation:
Answer:
F = 196.2 N
Explanation:
Use Newtons law
F = m * a
F = 20 kg * 9.81 m/s²
F = 196.2 N
Answer:
Explanation:
Using weight formula:
The mass of the box is 20 kg.
The acceleration of gravity on Earth is 9.81 m/s².
The weight of the box is 196.2 N.
The net force of the box is zero, since the box is at rest. The normal force is exerted upward on it by the table.
Răspuns:
1000 kg
Explicaţie:
Date date
t1 = 10 ° C
t2 = 293,15K = până la grad = 293,15-273 = 20,15 ° C
= 20 ° C aproximativ
Q = 418kJ = 418000J
c = 4180J / kg ° C
m =? Kg
Necesar:
Masa m în kg
Pasul doi:
Formulă:
Q = c * m * Δt
Q = c * m * (t2 -t1)
m = Q / c * (t2-t1)
Calculati:
m = 418000/4180 * (20-10)
m = 100 * 10 kg
m = 1000 kg
