Answer:the wave lengths are shorter and faster
Explanation:
Plato
The solution for the problem is:
1 Watt = 1 Joule per second
1 Watt*second = 1 Joule
a Kilowatt is 1,000 Watts
an hour is 60 seconds times 60 minutes or 3,600 seconds
a Kilowatt * hour is 1,000 Watts in 3,600 seconds
15 W*h = 15,000 Watt*hour = 15,000 Watt * 3,600 seconds = 54,000,000
Watt*second
54,000,000 Watt*second = ? Joules
54,000,000 Joules / second = 54,000,000 Watts
First, we have to figure out how many square meters there are in 29,000 acres.
29,000 acres * 4047^2 = <span>117,363,000 m^2
Now to find the burn rate in minutes, we must find how many minutes there are in a week.
7 * 24 = 168 (hours)
168 * 60 = 10,080 (Minutes)
</span>117,363,000 / 10,080 = 11,643
About <span>11,643m^2 of forest were burned every minute.</span>
Answer:b speed with displacement
Explanation:
Given: Plank's constant h = 6.626 x 10⁻³⁴ J.s
Speed of light c = 2.998 x 10⁸ m/s
Wavelength λ = 500 nm convert to meter = 5 x 10⁻⁷ m
Required: Energy E =?
Formula: E = hc/λ
E = (6.626 X 10⁻³⁴ J.s)(2.998 X 10⁸ m/s)/5 x 10⁻⁷ m
E = 3.97 X 10⁻¹⁹ J or in termS of electron volt
E = 2.48 eV
