Answer:
A battery is made up of three parts. The Cathode (positive end +) , the Anode (negative end -) and the electrolyte. The electrolyte allows electrical charges to travel between the cathode and anode. This chemical reactions creates the flow of electricity supplying the electrical voltage potential to power a circuit.
Typical materials of a battery are as follows
- Anode most often is made of zinc
- Manganese dioxide acting as Cathode.
- the electrolyte between and inside contains ions
Explanation:
Answer:
A=0.199
Explanation:
We are given that
Mass of spring=m=450 g=
Where 1 kg=1000 g
Frequency of oscillation=
Total energy of the oscillation=0.51 J
We have to find the amplitude of oscillations.
Energy of oscillator=
Where =Angular frequency
A=Amplitude
Using the formula
Hence, the amplitude of oscillation=A=0.199
The shadow forms on the first surface away from the shuttle in the direction opposite the sun.
Answer:
It spreads out into multiple shadow regions
Explanation:
- when the waves meet the barrier than light is diffracted as When this occurs, the wave bends around the corners of the barrier or passes through the opening of the wedge, which acts as a barrier, forming several patterns with the hole shape of the wedge.
- and The main condition for this phenomenon to occur is that the magnitude of the barrier must be equal to the magnitude of the wavelength.
- when sunlight as an electromagnetic waves is passes by key hole of gate, then this light will break and form many keyhole-shaped shadow fields.
Answer:
the angular acceleration of the gate is approximately 1.61
Explanation:
Recall the formula that connects the net torque with the moment of inertia of a rotating object about its axis of rotation, and the angular acceleration (similar to Newton's second law with net force, mass, and linear acceleration):
In our case, both forces contribute to the same direction of torque, so we can add their torques up and get the net torque on the gate:
Now we use this value to obtain the angular acceleration by using the given moment of inertia of the rotating gate:
