As weight =w =mg
g= gravitational acceleration on mercury = 3.7m/sec2
Mass of person =m= 70 kg
So w =(70kg)(3.7m/sec2)
w= 259 kgm/sec2
W= 259 N
Answer:
1.5 * 10^-2 Tm^2
Explanation:
Electric Flux = B.A cos(theta)
B = 0.055 T
A = 0.32 m^2
theta = 30
Electric Flux = (0.055 T).(0.32 m^2).Cos(30) = 0.0152 = 1.5 * 10^-2 Tm^2
<span>The answer is transformer. They utilize
electromagnetic induction to generate current. This is only possible in
alternating current due to the differential increase and decrease of electrical
current that induces changes in magnetic flux in the coil. This varies the
magnetic flux of the primary coil that generates current in the secondary coil.</span>
Answer:
<em> It takes 186.67 second for the light to travel from Mars to earth.</em>
Explanation:
Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.
S = d/t .......................... Equation 1
making t the subject of the equation
t = d/S ......................... Equation 2
Where S = speed of light, d = distance between the earth and Mars, t = time
<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>
<em>Substituting these values into equation 2</em>
<em>t = 56000000/300000</em>
<em>t = 186.67 seconds.</em>
<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>
