Answer:
Current in the battery will be 11.7 A
Explanation:
We have given that the there is parallel circuit with three different branches.
Current in each branch is 
, 
,
We have to find the current I in the battery
It is known that in parallel circuit current is sum of current in each branches
So current in the battery will be equal to
Therefore current in the battery will be 11.7 A
Explanation:
Physicists are scientist that studies physics. Physics is an aspect of physical science that seeks to understand the fundamental laws that governs how matter and energy interacts.
- Physics is a very broad science discipline and it uses the scientific method to investigate natural phenomenon.
- Applied physics deals with adapting physical solutions to provide technological solutions.
- Theoretical physics uses mathematical approaches to solve physics related problems.
- Experimental physics uses laboratory experiments for investigation.

Answer:
6.45×10¯²⁶ J
Explanation:
From the question given above, the following data were obtained:
Frequency (f) = 97.3 MHz
Energy (E) =?
Next, we shall convert 97.3 MHz to Hz. This can be obtained as follow:
1 MHz = 1×10⁶ Hz
Therefore,
97.3 MHz = 97.3 MHz × 1×10⁶ Hz / 1 MHz
97.3 MHz = 9.73×10⁷ Hz
Thus, 97.3 MHz is equivalent to 9.73×10⁷ Hz.
Finally, we shall determine the energy at which the frequency is broadcasting. This can be obtained as follow:
Frequency (f) = 9.73×10⁷ Hz
Planck's constant (h) = 6.63×10¯³⁴ Js
Energy (E) =?
E = hf
E = 6.63×10¯³⁴ × 9.73×10⁷
E = 6.45×10¯²⁶ J
Therefore, the energy at which the frequency is broadcasting is 6.45×10¯²⁶ J

the average reaction time is 0.25 seconds.
Answer:
The gravitational force is 
Explanation:
Given that,
Mass of large ball = 8.4 kg
Mass of small ball = 0.061 kg
Separation = 0.057 m
Gravitational constant 
We need to calculate the gravitational force
Using formula of gravitational force
Put the value into the formula
Hence, The gravitational force is
