-A crane raises a load by a cable. If the total mass of the load is 1500kg and the tension in the cable is 23500N, calculate the upwards acceleration of the load.
-An astronaut has a mass of 80kg. His weight on the moon is 128N. The astronaut holds a camera of mass 1.5kg and is allowed to fall freely on the planet. Calculate its acceleration.
If the wavelength of light is 400 nanometers in a substance where the speed of light is 2.35 x 108 meter per second, evaluate the wavelength of this light in air
When a tuning fork of frequency 360 Hz is held above a tube filled with water the resonances are found when the water level is at 25cm and 75cm
When a potential difference of 20V is applied to a given wire, it conducts 0.36A of current. What is the resistance of the wire
Two small metallic spheres, each of mass 0.20g, are suspended as pendulums by light strings from a common point.
a long pipe of outer radius 3.40cm and inner radius 2.89cm carries a uniform charge density of 3.22mcm3. using gausss
The velocity of the car at the end of the fifteen-second period is +20.6 m/s. The ratio of the average acceleration values is a1/a2 = 1.50. Find out the velocity of the car at the end of the initial ten-second interval.
A constant force is applied to an object, causing the object to accelerate at 10 m/s2. What will the acceleration be if the force is halved? What will the acceleration be if the object's mass is halved?
