Answer:
49.06 Newtons
Explanation: Using Newton's Second Law of Physics, F=ma
the mass of the car is 22.3kg and the acceleration of the object is 2.2m/s^2 then you would multiply the two and get 49.06 Newtons. You want the acceleration to be in m/s^2
Answer:
The charge must be negative
Explanation:
Hi!
The direction of the electric field of a charge depends on the sign of the charge, when it is positive, the electric field points outwards the charge but when it is negative, it points towards the charge. (As you can seen on teh attached image)
So, if on the faces of the box, the non-zero elecric field points inwards, it must mean that the total charge inside the box must be negative
The intensity of sound is just like the force of gravity, the force between electric charges, and the intensity of light . . . they all DEcrease at the same rate that the SQUARE of the distance INcreases.
So if two people are watching or listening to the same source, and one intensity is 1/10 as intense as the other intensity, then the farther person must be √10 times as far from the source as the nearer person is.
√10 = 3.1622 ...
So the second guy is about <em>3.16 miles</em> from the fire truck.
Answer:Greenhouse effect
Explanation:
Short wavelength radiation from the sun passes through a planet's atmosphere but some of the outgoing long-wavelength energy is absorbed and radiated again this process is known as Green house effect which increases the temperature of earth and as a result causes more to be trapped inside earth atmosphere.
1000/48 is 20.83 so the answer would be 20.83 meters/second
