Answer:
ΔT = 1.22*10^-3 °C
Explanation:
First, you calculate the potential energy of the bird when it is at 35 m high. The potential energy is also the mechanical energy of the bird in this case.
m: mass of the bird = 0.75kg
g: gravitational constant = 9.8m/s^2
h: height = 35m
All this energy is given to the water. You use the following formula in order to calculate the change in temperature:
m: mass of the water = 50kg
c: specific heat of water = 4186 J/kg°C
Q is equal to U (potential energy of the bird) because the bird gives all its energy to water. By doing ΔT the subject of the formula you obtain:
hence, the maximum rise in temperature is 0.00122 °C
Answer:
option C (1 and 4)
Explanation:
Like poles repel each other, unlike poles attract each other
In a homogeneous mixture, the ingredients are distributed evenly throughout the mixture, while in a heterogeneous mixture, the ingredients are unevenly distributed.
The action that will cause the magnetic force to push two magnets closer together: is that of attraction which happens when opposite poles of the magnets approach.
<h3>Meaning of
magnetic force</h3>
magnetic force can be defined as the effect that is felt by magnetic objects that causes attraction and repulsion.
A magnetic force attracts two magnets when they are in opposite poles and repels them if they are in the same pole.
In conclusion, The action that will cause the magnetic force to push two magnets closer together: is that of attraction which happens when opposite poles of the magnets approach.
