Answer:
The sport utility vehicle was traveling at V2= 11.5 m/s.
Explanation:
m1= 1090 kg
V1= 30.4 m/s
m2= 2880 kg
V2= ?
m1*V1 = m2*V2
V2= (m1*V1)/m2
V2= 11.5 m/s
Answer:
It controls the amount of current.
Explanation:
A resistor helps control and maintain the circuit which is it's main function.
Answer:
E = 1.24MeV
Explanation:
The photon travels at the speed of light, 3.0 × 
m/s, and given that its frequency = 1 picometer = 1.0 × 
m.
Its energy can be determined by;
E = hf
= (hc) ÷ λ
where E is the energy, h is the Planck's constant, 6.626 × 
Js, c is the speed of the light and f is its frequency.
Therefore,
E = (6.626 × × 3.0 × ) ÷ 1.0 ×
= 1.9878 × 
÷ 1.0 ×
E = 1.9878 × 
J
But, 1 eV = 1.6 × 
J. So that;
E = 
= 1242375 eV
∴ E = 1.24MeV
The energy of the photon is 1.24MeV.
Answer:
The speed of light is faster in water. The Refractive index of water is 1.3 and the refractive index of glass is 1.5. From the equation n = c/v, we know that the refractive index of a medium is inversely proportional to the velocity of light in that medium. Hence, light travels faster in water.
Temperature measures how much kinetic energy molecules have. The faster the kinetic energy, the higher the temperature.
