Answer:
36 grams of water
Explanation:
mass of H2O = 0.5 x 18 = 9g
Answer:
Explanation:
Height covered = 12m
time to fall by 12 m
s = 1/2 gt²
12 = 1/2 g t²
t = 1.565 s
Horizontal distance of throw
= 8.5 x 1.565
= 13.3 m
This distance is to be covered by dog during the time ball falls ie 1.565 s
Speed of dog required = 13.3 / 1.565
= 8.5 m /s
b ) dog will catch the ball at a distance of 13.3 m .
When a relationship between two different things is shown in a fraction it is a ratio.
hope this helps :)
D) Less than 20.
Explanation:
Equivalent resistance in a parallel combination is less than their individual value.
I think all of those are examples
