Answer:b
Explanation:
Object will be stable if its center of gravity lies over its base of support.
If the center of gravity is above the center of buoyancy then it provides positive righting moment and the object floats over the liquid and such object is said to possess positive meta-centric height.
Answer: 0.455 m/s^2
Explanation:
f = ma = m x 9.8=689 (the mass is constant)
m = 78.3
now on the elevator
f = 721 = m x a
a= 10.26
the elevator is moving down because there is a increase in weight. the acceleration of elevator = 10.26-9.8 = 0.455
Is this a chemistry question ?
Actually Welcome to the Concept of the Kinematics.
1.) Distance travelled = 15+20 = 35 miles.
Ai the total distance covered is 35 miles.
2.) Displacement is the shortest distance from the initial point to the final point.
here it's ==> 20-15 = 5 miles
hence, displacement = 5 miles
Answer:
Solar energy - Chemical energy - Electrical energy
Explanation:
A photovoltaic is a device which operates with respect to its exposure to radiation or light. This property determines its applications in electronics.
The energy from sunlight is in the form of solar energy, which get absorbed by the photovoltaic cell. The cell transforms the solar energy and store it as chemical energy. This is now finally transformed majorly into electrical energy as the output energy from the cell. Some amount of heat energy is produced in the process.
