Answer:
1317.52 Newton
Explanation:
Mass of sensor = m = 129 kg
Acceleration of the sensor = a = 2.84 m/s²
g = Acceleration due to gravity = 9.81 m/s²
= Force on the laser sensor due to motion = 129×2.84 = 366.36 N
= Force due to gravity on the laser = mg = 129×9.81 = 1265.49 N
Tension in the cable
∴ The tension in the cable towing the sensor is 1317.52 Newton
Mass is the physical quantity
Stars are located at a distance which are measured in terms of light years. Light year is an Astronomical unit used to measure distance between distant Celestial bodies.
1 light year = 9460730472580<span>800 metres
But no star is located at a distance of 1 light year. Some stars are located at millions of light years and light travels ~ 3 x 10</span>⁸ m/s. Thus light takes time to reach our atmosphere.
Answer:
Explanation:
Volume of lead object = volume of aluminium object = V
mass of lead object > mass of aluminium object
When both the objects immersed in water, the buoyant force acting on both the objects.
Buoyant force = Volume immersed x density of water x gravity
As the volume of both the objects is same, so the buoyant force acting on both the objects is same.
So, weight in air of lead object is more than the weight in air of aluminium object.
