The answer is D. earth's magnetic field
Answer:100 K
Explanation:
We know that Freezing Point of water is
at 1 atm
Converting it to Kelvin we get 273.15 K
Boiling Point of water is
converting it to Kelvin we get 373.15 K
Difference in the number we get =373.15-273.15=100 K
Temperature difference is independent of degree and will remain same for Celsius and Kelvin
Answer:
This is due to difference in bandwidths of different stations, and the inability of the bunny ear to accommodate distant bandwidths most times at the same time.
Explanation:
Bunny ears are a simple half-wave dipole antenna used to receive VHF television bands. It is constructed of two telescoping rods attached to a base, these rods extend out to about 1 meter length, and are collapsible when not in use. For the best reception the rods should be adjusted to be a little less than 1/4 wavelength at the frequency of the television channel being received and bandwidth of different station differs one frone another, so adjustment has to be made sometimes in order to get reception from other stations. Thankfully, the dipole has a wide bandwidth, so most times, adequate reception is achieved without having to adjust the length of the bunny ear.
The half wave dipole of a bunny ear has a low gain of about 2.14 dBi; which means it is not as directional and sensitive to distant stations as a large rooftop antenna, but its wide angle reception pattern may allow it to receive several stations located in different directions without requiring readjustment when the channel is changed. Sometime an adjustment of the rods is necessary.

Answer:
Explanation:
Answer:
Option D: Four times the original speed.
Explanation:
A centripetal force accelerates a body by changing the direction of the body's velocity without changing the body's speed.
The speed(v) is therefore constant, thereby making the magnitudes of the of the acceleration and the force constant.
The formula used to calculate the Centripetal force is given below:

where F represents the Centripetal force, m represents the mass of the moving body, v represents the speed or velocity at which the body is moving and r represents the radius.
Making the speed the subject of the formula: 
Therefore, when the radius (r) is changed to 4r, i.e r = 4r
speed(v) becomes 
After comparing, the difference between the speeds is Four times the original speed.
