The electricity would stop flowing through the wire and the battery would stop charging
Answer:
the keys will make it back to John.
Explanation:
In order to find out if the keys will reach John or not, we can use the formula of projectile motion to find the maximum height reached by the keys:
H = V²Sin²θ/2g
where,
V = Launch Speed = 18 m/s
θ = Launch Angle = 40°
g = 9.8 m/s²
Therefore,
H = (18 m/s)²[Sin 40°]²/(2)(9.8 m/s²)
H = 6.83 m
Hence, the maximum height that can be reached by the projectile or the keys is greater than the height of John's Balcony(5.33 m).
<u>Therefore, the keys will make it back to John.</u>
Answer:
.5 units north
<em><u>or</u></em>
55 ft/minutes(<em>squared</em>) north
Explanation:
.5 is what your info gives me but if i take that the average distance a block is it is 660ft than the answer is 55.
The force of Earth's gravity on you is greatest when you stand as
close as you can to the center of the Earth (but not underground).
From the choices listed, that would be (c).
Answer:
gravitational acceleration is 24.69 m/s²
Explanation:
given data
length = 0.81
time = 1.138 s
to find out
gravitational acceleration
solution
we will apply here time formula that is express as
T = 2π × ................1
here t is time , l is length and g is gravitational acceleration
so put here all value and find g
g =
g =
g = 24.69
so gravitational acceleration is 24.69 m/s²
