Answer:
+ 3.0 m
Explanation:
displacement is shortest distance from fixed point O in particular direction . in diagram shortest distance at end from O is 3 m and it is right of O so +. HENCE +3.0m
Answer:
Violet color has the highest frequency.
Explanation:
Light: it can behave as particle and wave. It has both natures. Frequency is the characteristic of the wave. It is defined as how many waves can pass through at a point in a given interval of time. It is measured in hertz.
Red: It lies in the visible region of the light. it has the lowest frequency in the visible region of the light.
Violet: It lies in the visible region of the light. Every wave has some energy. The energy of the wave is directly proportional to the frequency of the wave. More the energy of the wave then more will be the frequency of the wave. Violet color has more energy. It has the highest frequency.
Answer:
because they dont know how big it willactually be? idk
or so deep dish can fit too
Answer:
Force F = 1535.86 N
the force necessary for his wife to hold onto their child during the collision is 1535.86 N
Explanation:
Given;
Mass of toddler m = 13 kg
Velocity v = 37 mi/h = 37 × 0.44704 m/s = 16.54 m/s
Impulse time t = 0.14 seconds
Using the impulse momentum equation,
Impulse = change in momentum
Ft = m(∆v)
Force F = m(∆v)/t
∆v = 16.54 m/s
F = 13×16.54/0.14
Force F = 1535.86 N
