Which of these reduces friction ball bearings
What is the value of 7 + 8 × 2?
23
If a ship is moving at 15 knots and it travels for 4 hours, how far has it traveled?
60 nautical miles.
What is the perimeter of a rectangle that is 10 meters long and 5 meters wide?
30 meters.
Which of the following best describes the principle of buoyancy?
An object submerged in a fluid experiences an upward force equal to the weight of the fluid
displaced.
What is the speed of sound in air at room temperature?
Approximately 343 meters per second.
If you have a circuit with a voltage of 12 volts and a resistance of 4 ohms, what is the current?
1
, 3 amperes (using Ohm’s law: \( I = \frac{V}{R} \)).
What is the function of a fuse in an electrical circuit?
To protect the circuit from excessive current flow.
In a hydraulic system, how is force multiplied?
By using different sizes of pistons to create pressure.
What is the formula for calculating the area of a triangle?
Area = \( \frac{1}{2} \times \text{base} \times \text{height} \).
If a wave travels at a frequency of 5 Hz and the wavelength is 2 meters, what is the wave speed?
10 meters per second (using the formula: speed = frequency × wavelength).
What is the primary purpose of a transformer?
To change the voltage level in an electrical circuit.
