B.
Sedimentary rocks are formed by the deposition of material so it contains layers and smaller rocks. It also is good for fossil preservation.
Answer:
570 J
Explanation:
im sorry im not sure about the rest but i hope this helps
Answer:
The acceleration is
Explanation:
From the question we are told that
The angle which the inclined plane make with horizontal is
The frictional coefficients are and
The force acting on the crate is mathematically represented as
Here f is the net force at which the crate is sliding down the plane which is mathematically represented as
is the force due to weight which is mathematically represented as
and the force due to friction which is mathematically represented as
So
substituting values
The units are not consistent - 1 m/s is not the same as 1 km/h.
First thing to do would be to convert from one unit of speed to the other, say km/h to m/s. There are 1000 meters (m) for every kilometer (km) and 3600 seconds (s) for every hour (h), so
So in fact 1 km/h is about 4 times slower than 1 m/s.
Answer:
(A) 2652.49 ohm (b) 91937.45311 Hz (c) (i) 12.022 A (II) 2.324 A
Explanation:
We have given resistance R = 10 ohm
Capacitance C = 1 nF
Inductance of the coil L = 3 mH
(A) Inductive reactance
Capacitive reactance
Impedance
(b) We know that resonance frequency
(c) (i) At resonance condition so only effective resistance is R
So maximum current
(ii) Current across the coil
