As we know that magnitude of the vector is 670 m
and it is inclined 25 degree with x axis
now we know that component of vector along x direction is given as
Part 2)
In order to find the other component of the vector we can use
Answer:
Explanation:
Wien's displacement law states that the radiation of the black body curve for different temperatures will give peak values at different wavelengths and this wavelength is related inversely to the temperature.
Formally the law of Wien displacement states that the black body's spectral radiation per unit of wavelength, will give peaks at the wavelength of 
which is given by the mathematical expression.
Here, b is proportionality constant with value of 
The wavelength of the peak of the Gaussian curve is inversely related to temperature in degree kelvin.
Answer:
A. Zero
Explanation:
The force on a coil of N turns, enclosing an area, A and carrying a current I in the presence of a magnetic field B, is :
F = N * I * A * B * sinθ
Where θ is the angle between the normal of the enclosed area and the magnetic field.
Since the normal of the area is parallel to the magnetic field, θ = 0
Hence:
F = NIABsin0
F = 0 or Zero
Answer:
1) Acids have a sour taste.
Acid formulas start with "H", contain hydrogen and some react with active metals in a single replacement reaction to give off hydrogen gas.
An acid will turn blue litmus paper red
All acids are SOLUBLE in water.
Acids have a pH below 7.
2) Bases are bitter to taste a bitter taste is characteristic of all bases.
trong bases are very corrosive and can burn the skin.
Bases may or may not be soluble in water Bases that can dissolve in water are called alkalis
They can conduct electricity.
Bases lose their basicity when mixed with acids.
3) i dont know how to do it on here sorry but its self explanitory!!

Explanation:
We need to use the formula P = IV, where P is the power, I is the current and V is the voltage.
When we substitute our values in, we get:
100 = 240I, and so I = 0.42 Amps
Now, we have to work out the Resistance in the circuit at the operating temperature.
We do this using the formula V = IR
240 = (100/240) x R, and we get R = 576 Ohms
Since the resistance has gone up by a factor of 16, all we have to do now is to divide this answer by 16 to get the resistance at room temperature.
576/16 = 36 Ohms
Hope I helped!! xx
