As you drive away from a radio transmitter, the radio signal you receive from the station is shifted to longer wavelengths.True
Eddi Din [679]

Answer:

True

Explanation:

The radio transmitter generates the radio frequency

As you move away from the radio transmitter, the radio frequency decreases

The relationship between frequency and wavelength is inverse

As the frequency decreases the wavelength of the radio signal increases

if the force of friction is acting on the sliding crate is 100 N how much force will be applied to maintain a constant velocity?
djverab [1.8K]
"Constant velocity" means zero acceleration, which means zero net force.  So there must be100N pulling on the crate to cancel the 100N of friction force.

An object having a mass of 11.0 g and a charge of 8.00 ✕ 10-5 C is placed in an electric field E with Ex = 5.70 ✕ 103 N/C, Ey =
dezoksy [38]

Answer : F_{x} = 45.6\times10^{-2}\ N, F_{y} = 3040\times10^{-5} N and F_{z} = 0\ N

Explanation :

Given that,

Charge of the object q = 8.00\times 10^{-5}\ C

Electric field in x-direction E_{x} = 5.70\times10^{3}\ N/C

Electric field in y- direction E_{y} = 380\ N/C

Electric field in z - direction E_{z} = 0

Now, using formula

F = q E

Now, the force on the object in x- direction

F_{x} = 8.00\times10^{-5} C \times5.70\times10^{3} N/C

F_{x} = 45.6\times10^{-2}\ N

The force on the object in y- direction

F_{y} = 8.00\times10^{-5}\ C\times 380\ N/C

F_{y} = 3040\times10^{-5} N

The force on the object in z- direction

F_{z} = 8.00\times10^{-5}\ C\times 0

F_{z} = 0\ N

Hence, this is the required solution.

Calculate the percent error of the distance to the moon.
Bess [88]

Answer:

Explanation:

Difference in the measurement by shuttle crew  Δ d = 238857 - 226316 miles

= 12541 miles

Actual measurement =  238857 miles

percentage error

= (12541 / 238857 ) x 100

= 5.25 %
