Answer:
a) 0.81 A
b) 0.33 A , 0.48 A
c) 10 Volts , 10 volts
Explanation:
= 30 Ω
= 21 Ω
= Voltage of the battery = 10 Volts
a)
Parallel combination of resistance is given as
Ω
= Total current flowing through the circuit
Total current flowing through the circuit is given as
A
b)
In parallel, Voltage remain same.
= Potential difference across R₁ = 10 Volts
= Potential difference across R₂ = 10 Volts
Current flowing through individual resistors is given as
A
A
c)
In parallel, Voltage remain same, hence
= = 10 Volts
Naturally occurring.
inorganic.
solid.
definite chemical composition.
ordered internal structure.
Answer:
v=2.13 m/s
Explanation:
Given that
L= 3 ft
We know that
1 ft = 0.3048 m
L=0.91 m
a= g/2
F= m a
F= m g/2 = K L
k= (mg)/(2L)
Now from energy conservation
Kinetic energy of train = potential energy of the spring
k= (mg)/(2L)
By putting the values
( take g =10 m/s²)
v=2.13 m/s
Answer:
C
Explanation:
Constellations are stellar patterns which are made out of bright stars which appears close to each other and can form a recognisable pattern.
But that does not mean these stars are actually close to each other. The sky that we see from Earth appears as a 2D representation of a 3D Space. If you look in a particular direction in sky you will see all the stars in that direction irrespective of their actual distance from the Earth and hence these stars can be practically very far from each other too.
Answer:
their weight difference
Explanation:
weight adds to kinetic energy. a heavier object will have a higher kinetic energy because the extra weight will slowly increase or decrease the velocity depending on if it's being sent down a decline or inclined plane
