Answer:
Explanation:
mass, m = 50 g
moment of inertia, I = 9 x 106-5 kg m^2
radius, r = 0.7 cm
(a) As it moving downwards
Let T be the tension in the string
T = m (g + a) .... (1)
where, a be the acceleration
τ = I α = T r
α = a / r
So, I x a / r = T x r
a = T r^2 / I
Substitute in equation (1) we get
a = m (g + a) r^2 / I
a = mgr^2 / (I - mr^2)
a = 0.050 x 9.8 x 0.007 x 0.007 / (9 x 10^-5 - 0.050 x 0.007 x 0.007)
a = 2.401 x 10^-5 / (87.55 x 10^-6)
a = 0.274 m/s^2
τ = I x α = I x a / r
τ = 9 x 10^-5 x 0.274 / 0.007
τ = 3.52 x 10^-3 Nm
(b) α = a / r
α = 0.274 / 0.007 = 39.14 rad/s^2
when two vectors are inclined at some angle to each other then the magnitude of resultant of two vectors is given as
here A and B are the magnitude of two vectors and theta is the angle between them
now here we know that two vectors are of magnitude 0.25 m/s^2 each and they are inclined at angle of 45 degree
now we will plug in all data above
A = B = 0.25
So the magnitude of resultant acceleration will be 0.46 m/s^2
Yes,it's true ok? So how have you been doing
Answer:
(a). The power delivered to the element is 187.68 mW
(b). The energy delivered to the element is 57.52 mJ.
Explanation:
Given that,
Charge
Voltage
Time t = 0.3 sec
We need to calculate the current
Using formula of current
Put the value of charge
(a).We need to calculate the power delivered to the element
Using formula of power
Put the value into the formula
Put the value of t
(b). We need to calculate the energy delivered to the element between 0 and 0.6 s
Using formula of energy
Put the value into the formula
Hence, (a). The power delivered to the element is 187.68 mW
(b). The energy delivered to the element is 57.52 mJ.
Answer:
c. Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
Explanation:
Given the information about dependence of planetesimal composition on distance from the Sun and the existence of the frost line resulted in two main types of planets in our Solar System: the inner rocky planets and the outer gas giants. I have learned that planetesimal formation through accretion, and the types of materials that condensed at that distance from the Sun, will lead to the formation of Rock, metal, and ices made of materials like water, ammonia, and methane condensed into a solid and grew large enough to gravitationally attract hydrogen and helium gas from the Solar Nebula.
