Answer: Noise above 70 dB can cause hearing damage
Explanation:
A., Because speed is constant unless you stop it, or slow down <span />
Answer:
The force of gravity = 40 N
Explanation:
Given that,
The mass of a ball, m = 10 kg
The acceleration due to gravity on the surface of Mars, a = 4 m/s²
We need to find the force of gravity of the ball on Mars. The force of gravity on an object is given by :
F = mg
Substitute all the values,
F = 10 kg × 4 m/s²
F = 40 N
Hence, the correct option is (B).
Answer: analog-to-digital
Explanation: Analog-to-digital converters as the name implies simply refers to components which are used to convert continuous analog signals into a discrete analog outputs so they it can be read and processed by a microprocessor. The microprocessors are unable to depict and read analog signals which could be gathered from sound, light or water wave sources. This wave sources are then sampled, processed and sorted into levels by the analog-to-digital converter before being sent to the microprocessor so that the waves can be read.
Answer:
The flux is 682.6 Wb.
Explanation:
Given that,
Vector field 
We need to calculate the flux
Using formula of flux
Put the value into the formula
Hence, The flux is 682.6 Wb.
