Answer:
12 ohms
Explanation:
Ohm's Law tells the relationship between voltage, current, and resistance.
It can be written in three different ways, depending on which ones you know,
and which one you want to find.
Here's the one we need:
Resistance = (voltage) divided by (current)
= (120 V) / (10 Amp)
= 12 ohms .
Answer:
v=53.3m/s
Explanation:
Ek=1/2mv²
7.81×10⁴=1/2×55.0v²
v= the square root of 7.81×10⁴/0.5×55.0
v=53.3m/s
C. is the answer because acceleration is the change in velocity in time while velocity is speed with a direction
Answer:
.
Explanation:
Let 
and 
denote the velocity of this hockey player before and after stopping, respectively. The question states that 
and implies that 
since the hockey player has come to a stop.
The duration of this acceleration is 
.
Since the acceleration of this hockey player was constant, SUVAT equation would apply. In particular, the SUVAT equation 
gives the displacement 
of this hockey player during that 
of acceleration:
.
In other words, this hockey player would have travelled while stopping.
