Answer:
the horizontal velocity while it was falling is 22.1 m/s.
Explanation:
Given;
height of fall, h = 16 m
horizontal distance, x = 40 m
The time to travel 16 m is calculated as;
The horizontal velocity is calculated as;
Therefore, the horizontal velocity while it was falling is 22.1 m/s.
Answer:
69000 V
Explanation:
E = Electric field =
d = Distance between plates = 2.3 cm
When we multiply the electric field strength and the distance between the plates of a capacitor we get the maximum voltage.
Maximum voltage is given by
The highest voltage the students can use is 69000 V
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
