Answer: option D
Explanation: students will need to make the ammeter a component built into their circuit so that electron flow through it to measure the current, by doing so, they have to connect the ammeter in series with the resistor hence making the same value of current flow through both the ammeter and the resistor.
The value of current on the ammeter is the value of current in the resistor which is the value of current flowing in the circuit as a whole.
Answer:
True
Explanation:
Gamma rays and X-rays are made of packets of energy (photons) without mass or charge, with high penetrating power such that they can pass through the human body and impinge on a photographic plate creating an image of the interior of the human body. They electromagnetic radiation of high energy and high frequency that emanate from some natural sources such as cosmic sun rays and radon gas.
Gamma rays and X-rays can be man made by use of man made electronic devices and radioactive elements
Gamma rays and X-rays find use in airport security scanning and imaging services for medical testing.
Answer/Explanation:
The mechanical energy is 200 joules. Mechanical energy is determined by adding the total kinetic energy by the total potential energy.
M = kp
100 + 100 = 200
Im not so sure but it should be the
instantaneous speed
Here's the solution :
Let's find the final velocity :
Initial velocity (u) = 0 (cuz it started from rest)
Final velocity (v) = 8 m/s
Time taken (t) = 10 sec
now, we know that :
Acceleration = 0.8 m/s²
