Answer:
Endothermic, because energy is absorbed (A)
Explanation:
The reaction that take place in the instant cold pack causes the surroundings around it, including the bag that contains it. When the bag loses heat to the cold pack, the cold pack absorbs the heat, thereby causing the environment (the bag) to be cold.
There are several information's of importance already given in the question. Based on those information's the answer can be deduced.
Volage = 19 V
Current = 5 A
Power = Voltage x Current
= 19 x 5
= 95 Watt
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the second option or 95 W.
Answer:
Increases the greenhouse effect and increases the absorption of radiation
Explanation:
An increase in carbon dioxide increases the greenhouse effect and increases the absorption of radiation emitted from Earth's surface. Carbon dioxide has the ability to absorb radiation emitted from Earth's surface. This is because carbon dioxide is an effective heat trapping greenhouse gas.
According to the statement of OHM's Law,
The current in an electric circuit is directly proportional to the voltage across that circuit. This means, larger the voltage , more will be the current flow. Mathematically this can be stated as:
I = V/R
Here 1/R is the constant of proportionality and R represents the Resistance of the circuit.
This equation is also stated in texts as:
V = IR
So, the correct answer is option A. Voltage
False. you have to find out how many seconds are in the 25 min. 60 x 25 is 1500sec. Then multiply 1500 by .75 to get 1,125m. There are 0.001 kilometers in a meter. Move the decimal point three spaces to convert m to km. 1,125m becomes 1.125km
