Answer:
Acceleration = a = -1.94 m/s^2
Explanation:
Weight of the bundle = W = mg
m = W/g = 473/9.8
m = 48.26 kg
There are two forces acting on the bundle such as tension in the upward direction and weight in the downward direction. So, according to newton’s second law of motion:
Sum of forces = ma
T - W = ma
a = (T – W)/m
a = (379 - 473)/48.26
a = -1.94 m/s^2
Negative sign shows that the acceleration is in the downward direction.
C.water vapor i hope i helped
Answer:
final temperature will be 0 degree C
Total amount of ice will be
total amount of water
Explanation:
After thermal equilibrium is achieved we can say that
Heat given by water = heat absorbed by ice cubes
so we will have
Heat given by water to reach 0 degree C
heat absorbed by ice cubes to reach 0 degree
so we will have
so here we can say that few amount of water will freeze here to balance the heat
so final temperature will be 0 degree C
Total amount of ice will be
total amount of water
Answer:
Hi, Since energy levels in the nucleus are much higher than those in the gas, the nucleus will cool down by emitting a more energetic electromagnetic wave called a gamma ray . Gamma ray emission causes no change in the number of particles in the nucleus meaning both the atomic number and mass number remain the same.
Convex.
Concave curved inward (like how a cave foes in) and convex curves outward. Reflected and refracted do not apply to a lens.
