Responda:
400 g
Explicação:
Dado o seguinte:
Deixe Mass (m1) = m em t1 = 45 ° C
Massa (m2) = 200g em t2 = 15 ° C
Equilíbrio térmico (T) = 35 ° C
Usando a relação:
m1 * C * ΔT = m2 * C * ΔT
Onde m1 e m2 são as massas; C = capacidade de calor específico da água e ΔT é a mudança de temperatura
m1 * ΔT = m2 * ΔT
m * (45 ° C - 35 ° C) = 200 * (35 ° C - 15 ° C)
10 * m = 200 * 20
10 * m = 4000
m = 4000/10
m = 400g
<span>Approximately 4.6 billion years ago, the solar system was a cloud of dust and gas known as a solar nebula. Gravity collapsed the material in on itself as it began to spin, forming the sun in the center of the nebula.
</span>With the rise of the sun, the remaining material began to clump up<span>. Small particles drew together, bound by the force of gravity, into larger particles. The solar wind swept away lighter elements, such as hydrogen and helium, from the closer regions, leaving only heavy, rocky materials to create </span>smaller terrestrial worlds<span> like Earth.

God did not create earth, it has been proven.
Answer: 5.21 s
Explanation:
Given
Helicopter ascends vertically with 
Height of helicopter 
When the package leaves the helicopter, it will have the same vertical velocity
Using equation of motion
So, package will take 5.21 s to reach the ground
B) All natural radiation is at a level low enough to be safe.
Jennifer
Explanation:
she has more mass which means she is using more force
