Answer:

B. 1.7A

Explanation:

R = Resistance

I = Current

V = Voltage (potential difference)

22+4.5 = 26.5

45/26.6= 1.698

Round 1.698 to the nearest hundredth: 1.7

The current of the circuit is 1.7

Answer:

According to Ohm's law ,

V = IR

where ,

V = Potential difference

I = Current flowing

R = Total resistance

here ,

R _{t} = 22Ω + 4.5Ω = 26.5Ω

( since , the resistors are connected in series )

Using Ohm's Law ,

45 = I(26.5) \\  I =  \frac{45}{26.5}  \\  \\ I = 2.5A \: (approx.)

Therefore , option ( 1 ) is correct.

hope helpful~

Two balls are rolling using the same force. Which law explains why the bowling ball will roll a shorter distance than a soccer b
8_murik_8 [283]

Answer:

newton's 2nd  law

Explanation:

In the first law, an object will not change its motion unless a force acts on it. In the second law, the force on an object is equal to its mass times its acceleration. In the third law, when two objects interact, they apply forces to each other of equal magnitude and opposite direction.

How far does light travel in the time it takes sound to travel 1 cm in air at 20°c?
kykrilka [37]
The speed of sound at 20^{\circ}C is approximately v=343 m/s. The distance covered by the sound wave is
s=1 cm=0.01 m
And the time it takes is
t= \frac{S}{v}= \frac{0.01 m}{343 m/s}=2.9 \cdot 10^{-5} s

Now we want to find how far the light travels during this time. Light travels at speed c=3 \cdot 10^8 m/s, therefore the distance it covers during this time is
S=ct = (3 \cdot 10^8 m/s)(2.9 \cdot 10^{-5} s)=8700 m

4. A bullet of mass 30 g is fired from a rifle of mass 5kg at a speed of 259m/s. 
Ostrovityanka [42]

Answer:

Rifle Momentum=7.77kg*m/s v'= 1.554 m/s

Explanation:

a) m1v1 + m2v2 = m1v1' + m2v2'

0+0 = 0.03*259 + P(rifle momentum)

solve for P

p= 7.77kg*m/s

b) 7.77= 5*v'

v'= 1.554 m/s
