Answer:

80 km/hr

Explanation:

We are given that

Total distance covered by the car=120 Km

Time taken by the car=90 minutes= $\frac{90}{60}=1.5 hour$

We have to find the speed of the car

We know that Speed= $\frac{Distance}{time}$

Substitute the value then, we get

Speed= $\frac{120}{1.5}=80 Km per hour$

Hence, the speed of the car=80 km per hour.

The distance covered in one orbit is equal to the circumference of earth.

Given that radius of earth is 3959 miles.

Circumference of earth= 2πr = 2*3.14*3959 = 24875.13 miles

Speed is 26,000 miles per hour.

Since, Velocity= Distance/Time

Time= Distance/Velocity = 24875.13/26000

Time = 0.9567 hours

Therefore,

Average hour per orbit is 0.957 approximately.

A 5.0-V battery is places in series with two 1.25-Ω resistors. Determine the current through each resistor.

Nuetrik [128]

Answer:

Current through each resistor is 2 A.

Explanation:

Given that,

Voltage of a battery, V = 5 volts

Resistance 1, R = 1.25 ohms

Resistance 2,R' = 1.25 ohms

Both resistors are connected in series. The equivalent resistance is given by :

R" = R + R'

R" = 1.25 + 1.25

R" = 2.5 ohms

The current flowing throughout all resistors is same in series combination of resistors. Current can be calculated using Ohm's law as :

$I=\dfrac{V}{R"}$

$I=\dfrac{5\ V}{2.5}$

I = 2 A

So, the current through each resistor is 2 A. Hence, this is the required solution.
