Answer:
6 voltage is applied by the batteries.
Explanation:
To solve this sort of problem involving current, resistance and voltage, we use the relation:<em> </em><em>Voltage</em><em>= </em><em>Current x Resistance</em>.
From the problem, the following have been given:
Resistance= 2.4 ohms.
Current= 2.5 amps.
Required: Voltage?
Fix the values of current and resistance into the relation:
Voltage= <em>2.5 x 2.4</em>
=6 volts.
A highly frequency sound wave corresponds to a high pitch sound
Answer:
a=1.25m/s²
Explanation:
GIVEN DATA
vi=10m/s
vf=15m/s
S=5m
TO FIND
a=?
SOLUTION
by using third equation of motion
2as=(vf)²-(vi)²
2a(5m)=(15m/s)²-(10m/s)²
10m×a=225m²/s²-100m²/s²
10m×a=125m²/s²
a=
a=12.5m/s²

Answer:
New_momentum = 750 [kg.m/s]
Explanation:
Momentum is defined as
M = mass* velocity
Original momentum
M_old = 100 Kg * 5 m/s = 500 [kg.m/s]
If the car pulls over and picks up two people. The mass of the car is now 150 kg, but the velocity stays the same.
New momentum
M_new = 150 Kg * 5 m/s = 750 [kg.m/s]
