What else can I help you with?
Does is take more force to pick up an object or slide it across the desk or floor?
It typically takes more force to slide an object across a surface than to pick it up. When sliding an object, you are working against friction which creates resistance, whereas when picking up an object, you primarily need to overcome gravity.
When we carry an object across a room without lifting it or setting it down we do no physical work on it?
Carrying an object without lifting or setting it down does not involve doing physical work on the object in the scientific sense. Work, in a physics context, requires a force to be applied over a distance. In this case, though you are transporting the object, the force applied is not acting over a distance in the vertical direction.
What is weight how does it feel and how do you feel it?
Weight is the measure of the force of gravity acting on an object. It can feel heavy or light depending on the amount of force exerted due to gravity on an object. You feel weight through the sensation of pressure or resistance on your body when you are supporting or carrying an object.
The ability to move or change an object or what a wave carries?
The ability to move or change an object is known as force. A force can cause an object to accelerate, decelerate, change direction, or deform. Waves carry energy and transmit it from one place to another without carrying matter with them.
Does reflection change in orientation?
Yes, reflection changes the orientation of an object by flipping it across an axis, such as a line, without changing its shape or size. The object appears as a mirror image of its original position.

Which activity can occur without the use of energy?
Movement of water across the cell membrane
When carrying an object keep your arms straight and the object away from your body?
false

How did vanderbilt spend his money?
On many flowers. He spent a lot of his time picking flowers for a living
What laboratory tool is used in picking very hot object?
The tongs.

Do we need friction to pick objects up?
Yes, friction is necessary for picking up objects because it provides the necessary grip between our fingers and the object to overcome gravitational forces and move the object. Without friction, our fingers would slide over the object and it would be difficult to lift or hold onto it.
Do not bend your knees when picking up an object?
Bending your knees when picking up an object helps to maintain a straight back and reduces strain on your lower back muscles. Keeping your back straight and using your leg muscles to lift the object can help prevent injuries and promote good posture.
Is a needle a fomite?
Yes, an inanimate object capable of carrying organisms.
