Answer:
The correct answer is B-25 V
Explanation:
We apply Ohm's Law, according to which:
V = i x R
V = 5A x 5Ω
V= 25 V
Being V the potential difference whose unit is the VOLT, i the current intensity (Ampere) and R the electrical resistance (ohm)
Ith air resistance acting on an object that has been dropped, the object will eventually reach a terminal velocity, which is around 53 m/s (195 km/h or 122 mph) for a human skydiver. ... (On the Moon, the gravitational acceleration is much less than on Earth, approximately 1.6 m/s2.)
F=ma
F=125 N
m= 50 kg
125=50a
a=2.5 m/s^2
Answer:
4.38 m/s^2
Explanation:
If,
Initial velocity(u) is 9.2 m/s
Final velocity (v) is 19.1 m/s
Distance moved(s) in that period is 32 m
Therefore we use the formula,
v^2 = u^2 + 2as
; (19.1)^2 = (9.2)^2 + 2(32)a...then move the variables without a to one side..,
; 280.17 = 64a...then divide both sides by 64
; Acceleration = 4.38 m/s^2
It is both.
