Answer:
C. A neap tide is the period halfway between tides when the tide changes direction.
Explanation:
- Crash Course has a good video on this.
Hi!
The energy of the block is 4 m/s
To calculate this, you need to use the equation for
kinetic energy. The block is sliding (i.e. it's moving). If the object is sliding across a level surface, the only energy it has is kinetic energy, because
there is no change in potential energy (which changes with height). So, the mechanical energy will be pure kinetic energy. The equation is the following, derived from the expression for kinetic energy:
Have a nice day!
Answer:
The direction of current in the second wire will be upward.
Explanation:
We first need to find the direction of the magnetic field due to the first wire using the right-hand thumb rule.
Knowing that, one can easily find the direction of the second wire by using the right-hand rule.
The force per unit length on wire 2 due to wire 1 is given by,
Therefore,

Answer:
not moving
static actually means lacking in movement or action❤
