If the period wave is 6 seconds what is its frequency

Answers

Answer 1
Answer:

Answer:

.17Hz

Explanation:

The formula for frequency is f= 1/T , where T is the period.

f = 1/6 and 1/6 ≈ .17

Energy Transformation

Answer:

Energy transfer is the movement of energy from one location to another. Energy transformation is when energy changes from one type to another. While energy can be transferred or transformed, the total energy always remains the same.

The shifting of the observed wavelength of light due to the motion of the source toward or away from the observer is called the _____________.

Answers

Answer:

doppler effect

Explanation:

When the relative motion of two bodies results in the wavelength becoming shorter this means that the bodies are getting closer. This is known as blue shift.

When the relative motion of two bodies results in the wavelength becoming longer this means that the bodies are getting farther. This is known as red shift.

Collectively this phenomenon is known as the Doppler effect.

Suppose your rub a balloon in your hair and it acquires a static charge of −2 × 10⁻⁹c. what is the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon? Coulomb’s constant is 9 × 10⁹ N · m²/c² . Answer in units of N/C

Answers

To find the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon, we can use Coulomb's law. Coulomb's law states that the electric field (E) created by a point charge is given by the equation E = k * (Q / r^2), where k is Coulomb's constant, Q is the charge, and r is the distance from the charge.

Given that the charge of the balloon is -2 × 10^(-9) C and the distance from the balloon is 1 m, we can substitute these values into the equation:

E = (9 × 10^9 N · m²/C²) * (-2 × 10^(-9) C) / (1 m)^2

Note that the negative sign indicates the direction of the electric field, which in this case is due north.

E ≈ -18 N/C

Therefore, the magnitude of the electric field created by the balloon at a location 1 m due north of the balloon is approximately 18 N/C.

A 7.5 kg block is placed on a table . If it's bottom surface area is 0.6m2 how much pressure does the block exert on the table top?

Answers

Pressure is defined as the force per unit area. This measurement is more convenient to use for describing a force exerted. The standard unit for pressure is Pascal. For this problem, force is the gravitational pull from the block. Calculations are as follows:

P = F/A where F = mg

F = 7.5 ( 9.81) = 73.6 N

P = 73.6 N / 0.6 m^2 = 122.6 Pa
