10km/hr or 80mph is the possible answer I can give
Answer:
The ceramic tile will stand the force of 5 N.
Explanation:
Step 1: Calculate the area (A) of the ceramic tile
We will use the formula for the area of a square.
A = 50 cm × 50 cm = 2500 cm²
Step 2: Convert "A" to in²
We will use the conversion factor 1 in² = 6.45 cm².
2500 cm² × 1 in²/6.45 cm² = 3.9 × 10² in²
Step 3: Calculate the pressure (P) exerted by a force (F) of 5 N
We will use the following expression.
P = F/A
P = 5 N / 3.9 × 10² in² = 0.013 N/in²
Since the pressure exerted would be less than the maximum pressure resisted (40 N/in²), the ceramic tile will stand the force of 5 N.
0.000006kgm/s
Explanation:
Given parameters:
Mass = 0.01g
Velocity = 0.6m/s
Unknown:
Momentum = ?
Solution:
The momentum of a body is the product of its mass and velocity. It is subject to the impact a body in motion will have .
Momentum = mass x velocity
The unit is in kgm/s
We need to convert the mass to kilograms:
1000g = 1kg
0.01g = x kg ; 0.00001kg
Input the parameter:
Momentum = 0.00001 x 0.6 = 0.000006kgm/s

<span>Commutator
is the moving part of the electric motor and periodically reverses the current
direction between the rotor and the external circuit.One end of the coil is
attached to each half of the commutator.
Commutator are used so when electricity flows through the circuit, the
coil will rotate continually in the same direction.</span>
