Answer:
166.67 N
Explanation:
Given:
Mass flow rate = 50 kg/min = 50 kg / 60 seconds = 0.833 kg/s
Initial velocity = 200 m/s
after striking the normal board the water will flow in the normal direction, thus the final velocity in the direction of the initial flow will be zero
therefore,
Force = (change in momentum)
or
Force = Initial momentum - final momentum
or
Force = 0.833 × 200 - 0.833 × 0
or
Force = 166.67 N
The option that is an exception about the properties of magnesium is the option;
<u>Is typically made from </u><u>stampings</u>
The reason why the option is an exception is given as follows:
- Magnesium is a nonferrous metal as it is usually combined with manganese, zinc and aluminum.
- Within the group of structural metals, magnesium is the lightest, having a high strength-to-weight ratio.
- Magnesium posses good dampening characteristics, and is capable of reducing vibration of mechanical parts.
<em />
<em>However</em>
- Magnesium parts used for vehicle construction are die cast, and not made from stampings because magnesium is more difficult to stamp compared to aluminum.
Therefore, the correct option for the statement that is an exception from the true statements about magnesium is magnesium; <u>is typically made from stampings</u>
