Answer:
t = 6.63 s
Explanation:
Given that,
Initial velocity of the puck, u = 7.3 m/s
Deacceleration of the puck, a = -1.1 m/s²
Distance traveled, d = 5 m
We need to find the time the goalie have to stop the puck. Using equation of motion.
v = u +at
v = 0 (stops)
So,
So, the required time is 6.63 seconds.
Answer: All drugs of abuse trigger a surge of dopamine
Explanation: It creates a rush of “wanting” in the brain. This makes us crave more drugs.
The amount of heat will be equal to Lm.
Where L is the latent heat of fusion and m is mass of the ice.
Latent heat of ice = 80cal/g.
So the amount of heat required here will be 35× 80cal
= 2,800 cal.
