The velocity of the wave is defined by the product of wavelength and frequency. The velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.
<h3>What is the velocity of the wave?</h3>
The velocity of the wave is defined by the product of wavelength and frequency. It is obtained from the formula of the wavelength which is given by;
Hence the velocity of a wave with a length of 10 m and frequency of 5hz will be 50 m/sec.

Answer:
A compass works by detecting the Earth's natural magnetic fields. ... This allows the needle to better react to nearby magnetic fields. Since opposites attract the southern pole of the needle is attracted to the Earth's natural magnetic north pole. This is how navigators are able to discern north.
Answer:
Current is half
Voltage is half
Explanation:
according to Ohms law V = IR
Case 1
I₁ = V / R
I₂ = V / (R+R) = V / 2R
∴ I₁ / I₂ = (V/R) / (V/2R)
=> I₁ / I₂ = (V/R) * (2R/V)
=> I₁ / I₂ = (2VR / RV)
I₁ / I₂ = 2
I₂ = I₁ / 2
The current through each resistor in the two-resistor circuit is half the current through the resistor in the one-resistor circuit (the circuit in Part A).
The voltage across each resistor in the two-resistor circuit is half the voltage across the resistor in the one-resistor circuit.
Solar energy and Hydro is the correct option.
<h3>Which sources provide energy nowadays?</h3>
Today's energy supply is provided by solar energy and Hydro as compared to our ancestors because our ancestors have no modern technology to obtain energy from sun and water. They get energy from burning of fossil fuels and biomass.
So we can conclude that solar energy and Hydro is the correct option.

Answer:
Longitudinal Mechanical Wave
Explanation:
Mechanical waves are the waves that require medium to propagate. And a longitudinal wave is a wave in which the vibration of the energy(here: mass specifically) is in the direction of propagation of wave.
Shock wave, strong pressure wave in any elastic medium such as air, water, or a solid substance, produced by supersonic aircraft, explosions, lightning, or other phenomena that create violent changes in pressure.
Shock waves travel faster than sound and their speed increases as the amplitude of the wave is increased but their intensity fades faster due to the fact that some of its energy gets expended in the form of heat due to the resistance of the medium.
