Heat the tea because the heat make the tea's particles move around more dissolving the sugar quicker
Conduction is the transfer of energy by collusion between the atoms and molecules in a material.
Answer
correct answer is C
Head-to-tail method
Here head-to-tail method is employed to determine resultant of vectors.
Let horizontal component be 1 and let vertical component be 2
To add these two vectors. Move vector 2 until its tail touches the head of 1. The tail of resultant of these two vectors touch the tail of vector 1 and head of resultant vector will touch the head of vector 2.
Answer:
4.49 dollars
Explanation:
i = 9 A, V = 240 V, t = 16 h
Energy = V x i x t = 240 x 9 x 16 = 34560 W h = 34.56 kWh
The cost of 1 kWh is 13 cents.
Cost of 34.56 kWh = 13 x 34.56 = 449.28 cents = 449.28 / 100 = 4.49 dollars
Answer:
Less than 18000N
Explanation:
Given
This question will be answered using Newton's third law.
Understanding this law, it implies that reaction force is equal and opposite to the force exerted.
This implies that;
If the force exerted on the ball is 18000N
the force exerted is -18000N
So, the option that answers the question is less than 18000N because -18000N < 18000N
