Answer:
Explanation:
The angular position of first intensity maxima is given by the expression
= λ / d where λ is wave length of light and d is slit separation
putting the values given in the problem. ,
.02 = λ₁ / D
Now wavelength has been increased to 2λ₁
angular separation of first maxima
= 2λ₁ /D
= 2 x .02
= .04 radians.
Hey!
NOTE-:
u= initial velocity
v= final velocity
g= acceleration due to gravity
t= time
u= 0
v= 49 m/s
t=?
g= 9.8 m/s^2
Using first equation of motion -
v-u=at
49-0= 9.8×t
49 = 9.8t
49/9.8= t
t= 5 second
Hope it helps...!!!
Answer:
B. chemical only.
Explanation:
In the process of respiration which is a chemical process where organic compound is released. In this process exergonic reaction takes place in which compound changes into different ones.
Following are the two types of respiration:-
1] Aerobic respiration:- In this type of respiration requirement of oxygen is more and energy released is more.
2] Anaerobic respiration:- In this type of respiration oxygen requirement is less and energy released is also less.
Answer:
1. The current will drop to half of its original value.
Explanation:
The problem can be solved by using Ohm's law:
where
V is the voltage across the circuit
R is the resistance of the circuit
I is the current
We can rewrite it as
In this problem, we have:
- the resistance of the circuit remains the same: R' = R
- the voltage is decreased to half of its original value: 
So, the new current will be
so, the current will drop to half of its original value.
There are several actions that can be used to increase the action force of a canoe that is moving through water. One can increase the rate of striking or strike harder than before with a bigger paddle. Using a lighter canoe can also be helpful for increasing the speed. I hope the answer comes to your help.
