Answer:
Explanation:
According to a free body diagram the forces in the horizontal direction on body 1 would be:
F₁ = a₁*m₁ = -N
and on body 2:
F₂ = a₂*m₂ = N - F
N: normal force between the two blocks
F: frictional force on block 2
Since the two blocks are moving together, they need to have the same acceleration:
a₁ = a₂
This gives two equations with two unknown. Solving for a and N gives:
case A:
|a| = 0.96 m/s²
|N| = 2.9 N
case B:
|a| = 0.644 m/s²
|N| = 3.86 N
Answer:
C2H6 up the road to be with its own in
<span>9000 Pascals
Looking on the internet, it appears that a human can only suck about 3 feet of water. So let's convert that measurement into a few more convenient units.
cmH2O = 36 * 2.54 = 91.44 cmH2O
cmHg = 91.44 * 0.73555912101486 = 67.26 mmHg
Pascal = 91.44 * 98.0665 = 8967 Pascals
PSI = 91.44 * 0.0142233 = 1.3 psi
Since we're dealing with science and the metric system is the most common system used in science, I'd recommend an answer of 9000 Pascals.</span>
The answer should be B. A half step
Answer:
c. turn downward
Explanation:
From the information given:
To find the tendency of the sander;
We need to apply the right-hand rule torque; whereby we consider the direction of the flywheel, the direction at which the torque is acting, and the movement of the sander toward the right.
Since the flywheel of the sander is in counterclockwise movement, hence the torque direction will be outward placing on the wall. However, provided that the movement of the sander is toward the right, then there exists an opposite force that turns downward which showcases the tendency in the sander is downward.
