Answer:
A.
The moon's gravitational pull on Earth causes water to bulge on two sides of the Earth.
The question has missing information! But, with the objects and their respectives masses and specific coefficiets and with the following explanation, the question can be aswered!
Answer:
The one which has the highest product of the mass by specific heat.
Explanation:
The heat is a way of "energy in motion", which means that is a way that energy can be exchanged between substances. This exchange occurs when there is a difference in the temperature of the substances that are in contact, and then, to achieve thermal equilibrium, one substance loses heat (the one with higher temperature) and had a decrease in temperature, and the other gain heat and had an increase of temperature.
The heat loss is the same heat gained, and it can be calculated. If the substance doesn't suffer a physical change (which is the case here), then:
Q = m*c*ΔT
Where Q is the heat, c is the specific heat, and ΔT is the temperature change. So, rearranged the expression:
ΔT = Q/(m*c)
Because Q is the same for all of the objects, the one that will experience the smallest temperature change is the one that has the highest value of m*c (because it is indirectly proportional to ΔT).
Answer: B
Explanation:
The reason its B because Ampere, unit of <u>electric current</u> in the International System of Units (SI), used by both scientists and technologists.
An <u>electric current</u> is a flow of electric charge in a circuit. More specifically, the electric current is the rate of charge flow past a given point in an electric circuit. The charge can be negatively charged electrons or positive charge carriers including protons, positive ions or holes.
