In projectile mtion, what is the x-component of the initial velocity? if V= Vi = 100 m/s and the angle with horizontal axis Θ = 60 degrees

Answers

Answer:

???????????????????????

Explanation:

The x - component of the initial velocity is given as:

Ux = Vi cos theta

Ux = 100cos 60

Ux = 50m/s

An object placed in water will float if the weight of the object is MORE THAN the buoyant force of the water.True
False

Answers

False


If the object weighs more than the buoyant force then the object will sink.

This is because the buoyant force "pushes" the object upwards and the weight of the object "pushes" the object downwards.  Since the force downwards is greater than the force upwards the item will sink, so this statement is False.

The forces acting on a falling leaf are

Answers

Answer:

Gravitational and resistance force.

Explanation:

The push or pull on any object which causes an object to move is called force. The forces can be of many types. The forces acting on the falling leaf are :

  • Gravitational force : The force that acts in downward direction is called the force of gravity. This force pulls every object towards it.
  • Resistance force/ normal : The force that act opposite to gravitational force is called the resistance force. It opposes the direction of motion of the leaf.
the forces acting on a leaf are gravity and air resistance.In some cases the only force acting on an object is gravity, if that occurs then its called freefall.
