Can someone help me pls

X = 4.0 A, Y = 12 V

Explanation:

The voltage drop across the resistor equals the voltage gain across the battery.

Y = 12 V

Using Ohm's law, the current in the circuit is:

V = IR

12 V = X (3.0 Ω)

X = 4.0 A

we're given that v₀ = 0 and a = 5.4 m/s². therefore, since v = at + v₀ for constant acceleration the equation for velocity is

after 28s,

m/s

which i would round to 150 m/s as my final answer

d. platinum would have the greatest temperature increase because it has the lowest specific heat.
