Answer:
The emf and internal resistance of the battery are 9 volt and 2.04 Ω
Explanation:
Given that,
First resistor
Power
Second resistor
Power
We need to calculate the emf and internal resistance
Using formula of emf
For first resistor
....(I)
For second resistor
.....(II)
From equation (I) and (II)
Using component of dividend rule
Now, Put the value of internal resistance in equation (I)
Hence, The emf and internal resistance of the battery are 9 volt and 2.04 Ω
Given:
u= 0.91 m/s
a=0.31m/s∧2
s= 0.61 m
s = ut +1/2(at∧2)
where s is the displacement of the object
u is the initial velocity
t is the time
a is the acceleration
Substituting the values
0.61=0.91×t +(0.31 ×t∧2)/2
0.61=0.91 t + 0.155 t∧2
t=0.61 secs
Consider the equation
<u>v=u +at
</u>
where v is the initial velocity
u is the initial velocity
a is the acceleration
t is the time
Substituting the values we get
v= 0.91 +(0.31×0.61)
v= 1.099 m/s
Answer:
<em>UP</em>
Explanation:
heat flows from higher level to lower level
( higher concentration to lower concentration )
and since temperature in above block is less than the lower block, the heat will flow from lower block to higher block .
( Up )
