Explanation:
Tea cools faster in a cup than in a kettle because when it is on a cup it is more spread out so the cooler air around it is able to cool down each molecule faster than if it were in a kettle which is cooling down slower because the tea is not a spread out
Answer:
2280 V
Explanation:
distance between the plates, d = 4 cm = 0.04 m
Electric field strength, E = 5.7 x 10^4 V/m
The formula for potential difference is given by
V = E x d
V = 5.7 x 10^4 x 0.04
V = 2280 V
thus, the potential difference between the plates is 2280 V.
We do not feel the gravitational forces from objects other than the Earth because they are weak.
Not sure we can open those image files, but I think it would be 6.3*10^0
Answer:
-19.4 m
Explanation:
Given:
a = -1.77 m/s²
t = 3.33 s
v = -8.77 m/s
Find: Δx
Δx = vt − ½ at²
Δx = (-8.77 m/s) (3.33 s) − ½ (-1.77 m/s²) (3.33 s)²
Δx = -19.4 m
