Answer:
Explanation:
Yes she is doing work. With or without the groceries, she is still doing work. She does more work with the groceries than without because Work is defined by F which is defined by mass. The mass increases with the groceries.
The work done is against the force of gravity.
Answer:
position 2
Explanation:
At position 2, the sprinter started running immediately he heard the sound of the gunshot. This shows that the sprinter accelerated from rest and moved with an increasing acceleration. The magnitude of the final force is higher than the magnitude of the initial force at position 2. Therefore, the difference between the final and initial forces (i.e. net force) is forward (or positive).
I believe the answer is valcanos because they release sulfur in to the air and other chemicals so it willl affect the anispher
The first reason is that in the past humans didn't necessarily see the connections between the oceans and thus labelled them that way separating them into 5 oceans and the names stuck to this day.
Secondly, while all the oceans of the world constitute one large Ocean, people need some way to identify each part of it since it is easier to think when we have different categories instead of one large category.
Hope that helped!
The correct answer is 0.67 h
The coil's induced emf is specified as e=0. 50 v.
i i = 0.55 A is the initial value of the current flow.
I f = 0.95 A is the total amount of current flowing.
The shift in current occurs in a period of time when dt = 0.40 s.
The self-inductance is determined as follows:
The current change rate is represented here by dI/dt.
Step 2 After entering the values,
As a result, the self-inductance is 0.67 H.
The definition of self inductance is the induction of a voltage in a wire that carries current when the current in the wire is changing. When there is self-inductance, a circuit's own changing current creates a magnetic field that causes a voltage to be induced.
