Answer: B. Hold and feed the infant while you supervise the activity of the older children.
Explanation: On one side, a two-month-old is too young to understand that he has to wait until you finish with your other activities so you are free to feed him. His needs are urgent. Of course he is also too young to take the bottle on his own. These are the reason why options A and D are incorrect. On the other side, the other two children also need your supervision. You have to take care of them and leave them alone is not a good option. This is why option C is incorrect. Taking all these things into account I find option B as the best answer.

Answer: The density and the temperature
Explanation:
Sound needs a medium to travel. The medium particles vibrate and transfer energy. Sound travels by compression and rarefaction of the medium particles. Thus, the speed of the sound varies with the density of the medium. If the medium is denser, the particles would be closer and energy would transmitted faster because there would be more rapid collisions which means that speed of the sound will be greater in a denser medium.Thus, speed of sound is fastest in solids than in liquids and is least in gases.
Speed of sound also depends on temperature. Greater the temperature, the particles would vibrate faster which would lead to again more inter particle collisions. Thus, the speed of sound would increase with increase in temperature.
current
Answer:
Look at the picture
Explanation:
Answer:Correct ans is alternating current(AC CURRENT)
Explanation:Most houses in the U.S use alternative current for lights,fridges e.t.c that why when you turn of a switch in a room that particular rooms light goes off it doesn't affect the other rooms like what a direct current will do
Well how about direct current you Ask?
direct currents are also used in most homes examples are door alarms smoke detectors e.t.c
b. 11 kg.
c. 110 kg.
d. 1100 kg.
e. none of the above
A lamb that weighs 110 N has a mass of around 11 kg. Hence, option B is correct except B all options are incorrect.
The mass of a physical body is a measure of its entire makeup. Inertia, or the body's resistance to acceleration when a net force is applied, is also measured by this term. The strength of a body's gravitational pull on other bodies is also influenced by its mass. The kilogram is the fundamental mass unit of the SI.
In physics and engineering, the weight of an object refers to the gravitational force that pulls on it. Weight is the term used in many widely used textbooks to describe the gravitational force acting on the object. Some people think of weight as a scalar quantity that gauges the gravitational force's strength.
According to the question, the given values are :
Weight, w = 110 N and,
Taking value of g = 10 m/s²
As we know that :
w = m × g
110 = m (10)
m = 11 kg
Hence, the mass of the lamb will be 11 kg.

2. How fast would a 0.25 kg football have to be traveling to have the same momentum as a 0.05 kg bullet travelling 500 m/s?
3. Sarah, who has a mass of 55 kg, is riding in a car at 20 m/s. She sees a cat crossing the street and slams on the brakes! Her seat-belt stops her from flying forward, bringing her to rest in 0.5 seconds. How much force did the seat-belt put on Sarah?
1)
P = mv
P=75 (18) = 1350 kg-m/s
2)
0.25 v= 0.05 (500)
V= 100 m/s
3)
∆ mv = F∆t
55(20) =F(0.5)
