Answer:
I = 3.42 A
Explanation:
Ohm's law gives a relationship between the potential difference and the current passing through a conductor. The formula of Ohm's Law is given as follows:
V = IR
where,
V = Voltage
I = Current
R = Resistance
Initially:
V = 14 volts
I = 4 A
R = ?
Therefore,
14 volts = (4 A)R
R = (14 volts)/(4 A)
R = 3.5 Ω
Now, when V becomes 12 volts and R remains constant:
V = IR
12 volts = I(3.5 Ω)
I = (12 volts)/(3.5 Ω)
<u>I = 3.42 A</u>
Answer:
3.55m/s^2
Explanation:
S = ut + 1/2at^2
S = 48m, u = 0, t = 5.2
48 = (0×5.2) + (1/2 × 5.2^2)a
48 = 13.52a
Dividing through by 13.52
a = 48/13.52
a = 3.55m/s^2
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged). If an atom gains or loses one or more electrons, it becomes an ion. If it gains one or more electrons, it now carries a net negative charge, and is thus "anionic."
Answer:
Explanation:
given,
length of the ship = 120 m
length of model of the ship = 4 m
Speed at which the ship travels = 70 km/h
speed of model = ?
by using froude's law
for dynamic similarities
hence, the velocity of model will be 12.78 km/h
