Answer:
6.8×10^6 m
Explanation:
f = velocity of light/ wavelength
440= 3×10^8 / wavelength
so
wavelength = 3×10^7/ 44
= 6.8×10^6 m
Answer:
a property of a moving body that the body has by virtue of its mass and motion and that is equal to the product of the body's mass and velocity
Explanation:
Formula:
Momentum: Mass x Velocity
Hope it helps!
F=ma
m=300g= 0.3kg
a= -0.205i +0.700j m/s2 = <-0205, 0.7>m/s2
Thus, F = 0.3<-0.205, 0.7> N
F = <-0.0615, 0.21> N
= -0.0615i N +0.2100j N
Answer:
the answer is that the circuit is open,
Explanation:
if you look towards the switch its off, or open meaning no current can flow
Answer: 35000 J or 35kJ
Explanation:
Use equation for kinetic energy : Ek=mV²/2
m=700 kg
V=10m/s
-------------------
Ek= 700kg*100m²7s²/2
Ek=35000 J=35kJ
