The height of the chairlift above the snow when the ski falls off is determined as 20.4 m.

The height of the chairlift is calculated from the principle of conservation of mechanical energy as shown below;

P.E = K.E

mgh = ¹/₂mv²

gh = ¹/₂v²

h = v²/2g

where;

h = (20)²/(2 x 9.8)

h = 20.4 m

Thus, the height of the chairlift above the snow when the ski falls off is determined as 20.4 m.

Answer:false

Explanation:

The reactance of the circuit will be 5.233×10⁻⁴ ohm. Inductive reactance is the product of 2 times π frequency and the coil inductance.

When alternating electricity passes through pure reactance, it causes a voltage drop that is 90 degrees out of phase with the current.

The letter “X” is used to represent reactance in mathematics, and it is measured in ohms.

The inductive reactance of a coil is calculated using the following formula:

Inductive reactance, or XL, is the product of 2 times p (pi), and the frequency of the ac current in hertz, and the coil inductance in henries.

XL= 2πfL

Where,

f {frequency)

L (Inductance)

The reactance of the circuit is found as;

[tex]\rm R_{new}=0.38[{(\frac{1}{60} )^2][/tex]

[tex]\rm R_{new}=1.055 \times 10^{-4} \ ohm[/tex]

The inductance of the circuit is;

[tex]\rm X_{new}=1.9(\frac{1}{60} )^2\\\\X_{new}= 5.233 \times 10^{-4}\ ohm[/tex]

Hence, the reactance of the circuit will be 5.233×10⁻⁴ ohm.

According to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².

The acceleration of a moving body can be calculated by dividing the force of the body by its mass.

According to this question, the mass of an object is 10 kg and the force is 10 newtons, then the acceleration can be calculated as follows:

acceleration = 10N ÷ 10kg

acceleration = 1m/s²

Therefore, according to Newton's second Law of motion, if the mass of an object is 10 kg and the force is 10 newtons, then the acceleration is 1m/s².

Answer:

P = E / t       definition of power is energy / unit time

1 W = 1 Joule / sec      definition of 1 Watt of power

E = 2.6E4 J/s * 30 s = 7.8E5 Joules = 780,000 Joules

The average power transferred to the solar panels by sunlight is 26 000 w. The average energy transferred to the solar panels in 30 seconds is 780,000 joules.

To calculate the average energy transferred to the solar panels in 30 seconds, we can use the equation:

Energy transferred = Power × Time

Given that the average power transferred to the solar panels is 26,000 watts and the time is 30 seconds, we can substitute these values into the equation:

Energy transferred = Power × Time

Energy transferred = 26,000 × 30

Energy transferred = 780,000 watt-seconds

Since the watt-second is equivalent to the joule (J), the energy transferred to the solar panels is 780,000 joules.

Therefore, the average energy transferred to the solar panels in 30 seconds is 780,000 joules.

Answer:

chemical energy is converted to electrical energy in a voltaic cell.

Answer:

The answer would be A

Explanation:

The acceleration of the snail will be 7/13 m/sec². The acceleration is found as the rate of change of the velocity.

The rate of change of velocity with respect to time is known as acceleration. According to Newton's second law, the eventual effect of all forces applied to a body is its acceleration.

The given data in the problem is;

v(t)=1.4ln(1’t²) inches per minute

0<t<15 minute

Acceleration is found as;

[tex]\rm v('t)=1.4 \times \frac{1}{1+t^2} (2t)[/tex]

Acceleration at t= 5 minute;

[tex]\rm v'(5)=\frac{1.4(2)(5)}{1+5^2} =\frac{14}{26} \\\\ v'=\frac{7}{13}[/tex]

Hence, the acceleration of the snail will be 7/13 inch per square minute.

The sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.

Kirchhoff's loop rule states that the algebraic sum of potential differences, as well as the voltage supplied by the voltage sources and resistances, in any loop must be equal to zero.

In a series RLCcircuit, the voltages are not added by scalar addition but by vector addition.

Kirchhoff's loop rule is not violated since the voltages across different elements in the circuit are not at their maximum values.

Therefore, the sum of the maximum voltages across each element in a series RLC circuit is usually greater than the maximum applied voltage because voltages are added by vector addition.
