Answer:
v=115 m/s
or
v=414 km/h
Explanation:
Given data
To find
Terminal velocity (in meters per second and kilometers per hour)
Solution
At terminal speed the weight equal the drag force
For speed in km/h(kilometers per hour)
To convert m/s to km/h you need to multiply the speed value by 3.6
Sedimentary rocks are formed when sediment is deposited out of air, ice, wind, gravity, or water flows carrying the particles in suspension. This sediment is often formed when weathering and erosion break down a rock into loose material in a source area.
Answer:
violet region (UV) is wavelength less than 400 nm, the most common is between 200 and 400 nm,
The infrared (IR) range wavelengths greater than 700 nm
Explanation:
The spectral region near the visible is what humans can see with our eyes.
The range of the ultra violet region (UV) is wavelength less than 400 nm, the most common is between 200 and 400 nm, this radiation is responsible for tanning and skin burns.
The infrared (IR) range is a very wide range that begins at wavelengths greater than 700 nm and continues up to approximately 25,000 nm (1012 Hz).
Answer:
I = 4.38 x 10⁻⁷ A
Explanation:
Given,
speed = 4.47 x 10⁴ m/s
radius of the circular path, r = 2.59 x 10⁻⁹ m
effective current = ?
The current represented by the orbiting electron is equal to
f is the frequency
q is charge of electron
we know,
f = 2.74 x 10¹² Hz
now,
I = 4.38 x 10⁻⁷ A
Hence, the effective current associated with the orbiting electron is equal to I = 4.38 x 10⁻⁷ A
