Answer:
Weight = 3.924 N
Bouyant force = 2.5N
Apperent weight= 1.424N
Explanation:
Radius of the sphere = 0.0165 m
Volume of sphere = (4πr³)/3
Volume = 4.189*(4.49*10^-6)
Volume = 1.88*10^-5
For the weight.
Mass = density* volume
Mass = 2.14*10^4 *(1.88*10^5)
Mass = 0.4 kg.
Weight = mass * acceleration due to gravity
Weight = 0.4*9.81
Weight = 3.924 N
For the buoyant force Fb
Fb = volume * density of fluid* acceleration
Fb = (1.88*10^5)*1.36 × 10^ 4*9.81
Fb = 2.5N
For Apperent weight
True weight - buoyant force = Apperent weight.
3.924- 2.5N= 1.424N
Answer:
Explanation:
Given
Cross of two Product gives a vector which is perpendicular to the both vectors
Now unit vector in this direction is given by
Radiation and Convection transfer energy from the core to the photosphere. This is because energy from the core moves through a thick layer called the radiative zone. Also in the convection zone energy moves mainly by convection. Rising currents of hot gas in the convection zone carry energy toward the Sun's surface.
Answer:
A
Explanation:
The answer is A due to the gravity is stronger the greater the mass but the less the mass is the weaker the gravity. In conclusion, the answer is A because the strength of gravity depends on the mass.
