In this case, a moving golf club hits a stationary golf ball. We can use Newton's second and third laws to explain what happens

upon impact. One statement is INCORRECT.
A)The club and the golf ball experience equal accelerations.
B)The golf ball experiences a greater acceleration due to its smaller mass.
C)The forces on the club and ball are equal in magnitude and opposite in direction
.D)The force experienced by the club head is equal to the force experienced by the golf ball.

two resistors of 20 ohm each are connected in a parallel with a battery of 10V. The total current passing through circuit is
Varvara68 [4.7K]

Answer:

1 Ampere.

Explanation:

From the question given above, the following data were obtained:

Resistor 1 (R₁) = 20 ohm

Resistor (R₂) = 20 ohm

Voltage (V) = 10 V

Current (I) =?

Next, we shall determine the equivalent resistance in the circuit. This can be obtained as follow:

Resistor 1 (R₁) = 20 ohm

Resistor (R₂) = 20 ohm

Equivalent Resistance (R) =?

Since the resistors are in parallel connection, the equivalent resistance can be obtained as follow:

R = (R₁ × R₂) / (R₁ + R₂)

R = (20 × 20) / (20 + 20)

R = 400 / 40

R = 10 ohm

Finally, we shall determine the total current in the circuit. This can be obtained as illustrated below:

Voltage (V) = 10 V

Equivalent Resistance (R) = 10 ohm

Current (I) =?

V = IR

10 = I × 10

Divide both side by 10

I = 10 / 10

I = 1 Ampere

Therefore, the total current in the circuit is 1 Ampere.

[30 POINTS] An automobile steering wheel is shown. The ideal mechanical advantage of this wheel and axle = _____ .
mamaluj [8]

Rw/Ra = MA

18cm/2cm= MA

MA = 9

This means that Fi is 1/9 of the force applied to the axil. The distance travelled by Rw is 9 times more than Ri  is that you move 9 times more when turning the wheel using Rw.

Put more simply

Rw/Ra = Fa/Fw

  • Rw = Radius of the wheel
  • Ra = Radius of the axil
  • Fa = Force delivered on the axil
  • Fw = Force delivered by the wheel
