Why might there be multiple foremen on one work site?

Remy noticed that after oiling his skateboard wheels, it was easier to reach the speeds he needed to perform tricks. How did the

Sidana [21]

Answer:

The oil reduced friction between the moving parts of the skateboard. ( A )

Explanation:

The oil reduced Friction between the moving parts of the skateboard and this is because the reduction in friction between moving parts causes an increase in speed.

Remy will oil the moving parts that connects the wheels of the skateboard to the Board, because this is where the most friction is found. the friction between the wheels and the ground cannot be affected by oiling the wheels

The correct option is;

c. Leaving the chuck key in the drill chuck

Explanation:

A Common safety issues with a drill press leaving the chuck key in the drill chuck

It is required that, before turning the drill press power on, ensure that chuck key is removed from the chuck. A self ejecting chuck key reduces the likelihood of the chuck key being accidentally left in the chuck.

It is also required to ensure that the switch is in the OFF position before turning plugging in the power cable

Be sure that the chuck key is removed from the chuck before turning on the power. Using a self-ejecting chuck key is a good way of insuring that the key is not left in the chuck accidentally. Also to avoid accidental starting, make sure the switch is in the OFF position before plugging in the cord. Always disconnect the drill from the power source when making repairs.

A motor car is travelling at 144km/h in a 90km/h speed zone .The driver suddenly sees speed camera 80m ahead before the camera c

Kruka [31]

The deceleration required to comply with the speed limit before being caught by the camera is 6.094 meters per square second.

Let assume that the motor car decelerates at constant rate. Given the initial and final speeds ( $v_{o}$ , $v$ ), in meters per second, and travelled distance ( $s$ ), in meters, the deceleration ( $a$ ), in meters per square second, is determined by this formula:

$a = \frac{v^{2}-v_{o}^{2}}{2\cdot s}$

If we know that $v_{o} = 25\,\frac{m}{s}$ , $v = 40\,\frac{m}{s}$ and $s = 80\,m$ , then the deceleration required to comply with the speed limit is:

$a = \frac{\left(25\,\frac{m}{s} \right)^{2}-\left(40\,\frac{m}{s} \right)^{2}}{2\cdot (80\,m)}$

$a = -6.094\,\frac{m}{s^{2}}$

The deceleration required to comply with the speed limit before being caught by the camera is 6.094 meters per square second.
