the key result indicate that how you will achieve the your goal
Answer:
65.1 °C
Explanation:
m = mass of the water = 0.5 kg
= initial temperature of water = 35.00 °C
= final temperature of water
c = specific heat of water = 4186 J/(kg °C)
Q = Amount of heat removed from water = 6.3 x 10⁴ J
Amount of heat removed from water is given as
Q = m c ( - )
Inserting the values
6.3 x 10⁴ = (0.5) (4186) ( - 35.00)
= 65.1 °C
Answer:
8-5=3

3N to the left
Explanation:
Answer:
Velocity = 8 ft/s
Acceleration = 0 m/s²
Explanation:
Since, the horse is moving with a constant velocity, whose magnitude is given as equal to 8 ft/s. Therefore, it will have the same velocity when it is 10 ft away from the barn. And the velocity of hay bale will be same as the velocity of horse, as the horse is carrying the bales. Therefore:
<u>Velocity = 8 ft/s</u>
Coming to the second part of the question, which relates to the acceleration of the hay bale, when horse is 10 ft away from the barn. The formula for acceleration is given as:
Acceleration = Change in Velocity/ Time
But, the velocity of the horse in constant, which means there is no change in velocity. Hence,
Change in Velocity = 0
Therefore,
Acceleration = 0/Time
<u>Acceleration 0 m/s²</u>
