The current will increase at the same rate the voltage does.
Answer: 1.776933x10^7
Explanation:
Moment of inertia I = 8.26x10^36kgm^2
Mass of planet m = 6.54x10^22kg
Also, Planet is solid sphere so that, Moment of inertia is I = _2_ m
R^2= 0.4 R^2 5
Where R is radius of planet
Putting into calculation
We get,
I = _2_ m R^2
5
8.26x10^36 = 0.4x6.54x10^22xR^2
8.26x10^14 = 2.616 R^2
R = 1.776933x10^7
Answer: B. The trace jumps down 1 division
Explanation:
From the above data, the two signals are combined and adjusted in the middle of the screen. If you switch the signal in channel B from DC to AC, then the screen jumps down 1 division.
Heat absorbed is given by multiplying the specific heat capacity with the mass of the substance and the change in temperature.
specific heat capacity of iron= 460.5 J/kg/k
therefore, heat = mcФ, where c is heat capacity, m is the mass of iron and Ф is change in temperature. Change in temperature is 14 (20-6), mass in kg (0.057 kg)
=460.5 × 0.057 x 14
= 367.48 joules
Hence, heat absorbed by iron will be 367.48 joules
Answer:
P = 6*5 = 30 [kg*m/s]
Explanation:
in order to solve this problem, we must remember that linear momentum is defined as the product of mass by Velocity. This way you can calculate the momentum using the following equation.
P = m*v
where:
P = lineal momentum [kg*m/s]
m = mass = 6 [kg]
v = velocity = 5 [m/s]
P = m*v
P = 6*5 = 30 [kg*m/s]
