You didn't post any choices. A microwave Photon carries more energy than a radio wave photon. An infrared Photon carries more energy than a microwave photon. A visible light Photon carries more energy than an infrared photon. An UltraViolet Photon carries more energy than a visible light photon. An x-ray Photon carries more energy than an UltraViolet photon. A gamma ray Photon carries more energy than an x-ray photon.
In order to find out what it should be the scientific notation, you've got to get it between 0.1 and 9.9, therefore, you've got to divide it by 10 million
46,500,000 / 10,000,000 = 4.65
This is then in the correct form, and you've then got to find the notation.
To do this, you need to keep dividing 10,000,000 until you get to 10.
10,000,000/10= 1,000,000/ 10= 100,000/ 10= 10,000/10= 1,000/ 10= 100/10= 10
You've divided it by ten six times, therefore, the scientific notation is 10^6.
Therefore, 46,500,000 in scientific notation is 4.65 x 10^6
Hope this helps :)
Answer:
Eifel Tower height will increase by 0.03888m
Explanation:
You can calculate the variation in height by using the coefficient of thermal expansion of the steel:
ΔH = H*α*ΔT
The coefficient of thermal expansion α is describes the change in length of an object after a change in temperature. the coefficient of thermal expansion of the steel depends on the composition of the steel, but in general, it has a value of around 
. Then, the variation in heigth will be equal to:
Calculate the time it takes for the car to reach the beginning of the hill given that acceleration as already found in part a is 2.89 m/s²
Answer:
5.88 s
Explanation:
Using kinematic equation, v=u+at where v and u are the final and initial velocities respectively, a is acceleration and t is time.
Considering the first part, acceleration is already found as 2.89 m/s and the final velocity is given as 17 m/s while the initial velocity is zero since it is at rest.
Making t the subject of formula then
t=(v-u)/a
Substituting the given figures then
t=(17-0)/2.89=5.8823529411764s
Rounded off, t=5.88 s
