Answer:
Txomin lifted the stone with greater mass. (Txomin levantó la roca con mayor fuerza).
Explanation:
The sportsman that lifts the stone with a greater mass needs a higher force (El deportista que levanta la piedra con mayor masa necesita una mayor fuerza):
José
Txomin
Txomin lifted the stone with greater mass. (Txomin levantó la roca con mayor fuerza).
Answer:
Height of the pool will be 4.004 m
Explanation:
We have given gauge pressure at the bottom
Density of water
We have to find the height of the pool
We know that gauge pressure is given by
h = 4.004 m
Height of the pool will be 4.004 m
Explanation:
Let's set the x-axis to be parallel to the and positive up the plane. Likewise, the y-axis will be positive upwards and perpendicular to the plane. As the problem stated, we are going to assume that m1 will move downwards so its acceleration is negative while m2 moves up so its acceleration is positive. There are two weight components pointing down the plane, and and two others pointing up the plane, the two tensions <em>T</em> along the strings. There is a normal force <em>N</em> pointing up from the plane and two pointing down, and . Now let's apply Newton's 2nd law to this problem:
<u>x-axis</u><u>:</u>
<u>y-axis</u><u>:</u>
Use Eqn 1 to solve for T,
Substitute this expression for T into Eqn 2,
Collecting all similar terms, we get

Answer:
1.76m/s²
Explanation:
Acceleration is the time rate of change in velocity of a body. It is a vector quantity that is it has both magnitude and direction
From newton's second law of motion which states that the rate of change of momentum of a body is proportional to the applied force which takes place in the direction of force applied.
This law gives a formula which relate force, mass and acceleration.
Force = mass x acceleration
Given that force = 9.7N , mass = 5.5kg
Since force(F)= mass(m) x acceleration(a)
Therefore F = ma
Divide both sides by m
F/m = ma/m
Therefore,
Acceleration (a) = F/m
Acceleration = 9.7N ➗ 5.5kg
Acceleration = 1.76m/s²
The S. I unit of acceleration is m/s²
