Answer:D: the velocity is zero
Explanation:
Answer:
first question is 178 g of sodium phosphate dihydrate. second question is 0.25 mL
Explanation:
To know the number of grams from the number of moles 
. 1 mol is equal to 178 g. Second question mL of the stock is obtained from 
.
The Force per meter on a straight wire carrying current in a magnetic field is<u> 0.045 N/m.</u>
<u>Calculation:-</u>
F/ℓ = B I sin θ
Where B – Magnetic field = 0.02 T I – Current = 5 A
Substituting the values
F/ℓ = (0.02) (5) (sin 27 deg)
F/ℓ = <u>0.045 N/m</u>
A force is an influence that can alternate the motion of an item. A force can cause an item with mass to trade its pace, i.e., to boost up. force can also be described intuitively as a push or a pull. A pressure has both value and course, making it a vector quantity.
The push or pull on an item with mass causes it to change its velocity. force is an external agent capable of converting a frame's nation of relaxation or motion. It has significance and a path. A force is a push or pulls among gadgets. it is called an interplay because if one object acts on some other, its movement is matched with the aid of a reaction from the alternative object.

We can solve the problem by using Ohm's law, which states that an Ohmic conductor the following relationship holds:
where
is the potential difference applied to the resistor
I is the current flowing through it
R is the resistance
In our problem, I=4.00 A and
, so the potential difference is
Increase in sea water pollution
