Answer:
Solution:
As per the question:
Mass of first object, m = 120 kg
Mass of second object, m' = 420 kg
Mass of the third object, M = 69.0 kg
Distance between the m and m', d = 0.380 m
Now,
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m:
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m':
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m and m':
Answer:
Liquid volume is usually measured using either a graduated cylinder or a buret. As the name implies, a graduated cylinder is a cylindrical glass or plastic tube sealed at one end, with a calibrated scale etched (or marked) on the outside wall.
Answer:
The work done is twice as great for block B because it is moved twice the ... Equal forces are used to move blocks A and B across the floor. ... Does the normal force of the floor pushing upward on the block do any work? ... Suppose that the mass is halfway between one of the extreme points of its motion and the center point.
Explanation:
Answer:
0.358 kg
Explanation:
From simple harmonic motion,
T = 2π√(m/k)................ Equation 1
Where T = period of the spring, k = spring constant of the spring, m = mass suspended, π = pie
make m the subject of the equation
m = kT²/4π².................. Equation 2
Given: k = 15 N/m, T = 0.97 s, π = 3.14
Substitute into equation 2
m = 15(0.97²)/(4×3.14²)
m = 14.1135/39.4384
m = 0.358 kg.
Hence mass suspended = 0.358 kg
