Solve this using Olm's law, which relates current (C), voltage (V), and resistance (R). Olm's law says:
I \: (current ) ={\frac {V \: (voltage) }{R\:(resistance)}}

We are told that voltage, V = 12V, and resistance, R = 4.8 <span>Ω. Plug these values into the equation and solve for current:
</span>I = \frac{V}{R}\\&#10;I = \frac{12}{4.8}\\&#10;I = 2.5A&#10;&#10;
<span>-----
Answer: Current = 2.5 Amperes</span>

A grape is thrown straight up in the air. If it was thrown at 2 m/s, how high will it go in the air?
ser-zykov [4K]

Answer:

Answer: <u>Height</u><u> </u><u>is</u><u> </u><u>0</u><u>.</u><u>2</u><u>0</u><u>4</u><u> </u><u>m</u>

Explanation:

At the highest point, it is called the maximum height.

• From third newton's equation of motion:

{ \rm{ {v}^{2}  =  {u}^{2}  + 2gs}}

• At maximum height, v is zero

• u is initial speed

• g is -9.8 m/s²

• s is the height

{ \rm{0 {}^{2}  =  {2}^{2}   -  (2 \times 9.8 \times s)}} \\  \\ { \rm{4 = 19.6s}} \\  \\ { \rm{s = 0.204 \: m}}
