2. False

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:

The balloon shrank because the average kinetic energy of the gas molecules in a balloon decreases when the temperature decreases. This makes the molecules move more slowly and have less frequent and weaker collisions with the inside wall of the balloon, which causes the balloon to shrink a little.

Explanation:

Not only does it shrink in cold water but it shrinks in the cold itself.

The spring constant of the spring if it would compress by 1 m to stop the ore car is 340,350.4 N/m.

The potential energy of the car is calculated as follows;

P.E = mgh

where;

sin (10) = h/L

h = L x sin(10)

P.E = mgLsin(10)

P.E = 2000 x 9.8 x 50 x sin(10)

P.E = 170,175.21

The potential energy of the car at the top of the incline will be converted  to the elastic potential energy spring at the bottom of the incline.

P.E = U = ¹/₂kx²

k = (2U)/x²

k = (2 x 170,175.2)/(1)²

As stream discharge increases, only velocity increases.

The discharge or volume flow rate is defined as the product of the velocity of the fluid and the area of cross- section of the pipe or tube.

Discharge Q = Area A x Velocity V

Q = AV

The discharge is directly proportional to the velocity of the fluid. When discharge increases, velocity is the only physical quantity that can be changed.

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

Acceleration is found as;

Explanation:

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.

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]
