The force that gravity exerts on an object is called weight.
The shape of a planet’s orbit is elliptical.
The second law of planetary motion states that each planet revolves so that an imaginary line connecting it to the sun sweeps over equal areas in equal time intervals.
Answer:
Force of 540 Kgm/s^2 is closest to the net force acting on the vehicle.
Explanation:
Force is the change in momentum per unit time
This relationship is equivalent to product of mass and acceleration
Thus F = Mass * acceleration
Substituting the given values in above equation we get -
F = 450 Kg * 1.2 m/s^2
F = 540 Kgm/s^2
Answer: C, Fungus X is a common mold and fungus Y is a Chytrid.
Explanation:
I just took the test
Answer:
The correct answer will be- false
Explanation:
The understanding of the biomechanics of the human movements is studied by the lever system which represents the rigid bar which comes on a fixed point as a result of the force exerted.
The lever systems are defined into three types into which the last lever system is the third lever system which is the recognized by the muscle (effort) in the middle of the joint (fulcrum) and the weight of the body (load).
These movements are related to the exercise like jumping, running and kicking which requires speed and distance to be covered. Thus, false is the correct answer.
the effort is the middle component and lies between the fulcrum and load.
