Answer:
0.04658 m from the nut
Explanation:
Recall that torque is defined as the vector product of force (F) times distance (d). Then, given that the force is applied perpendicular to the wrench, gives the sine of the angle (90 degrees) equal to 1, simplifying the calculation which consists basically on solving for d in the equation:
2.25 N*m = 48.3 N * d
d = 2.25 /48.3 m ≈ 0.04658 m
Answer:
B
Explanation:
Density = mass / volume
Less dense objects float to the surface so if the liquid becomes 1000 kg/m3 then it is the densest thing in the mixture, except for Q which has a density = to that of the water so it will stay in place around the middle, since the other two are more dense they will go to the bottom of the container.
Explanation:
We have,
According to attached figure, the height of the inclined plane is 60 m and force acting on the block is 10 N. It is required to find the work must be done against gravity to move it to the top of the incline. The work done is given by :
W = mgh
or
Hence, the correct option is (A) "600 J".
Answer:
Mass=0.143 kg
Explanation:
From the Newton's second law of motion the force applied to an object is directly proportional to the acceleration produced and the acceleration is in the direction of the force.
F=ma where F is the force, m is the mass of the object and a i the acceleration.
m=F/a
=4.719N/33 m/s²
=0.143 kg
