Gold and silver are used in making jewellery since ages. As a matter of fact, gold is used because of its fine lustre and rarity.
Gold doesn't tarnish and doesn't react with air as other metals like iron do. Furthermore, gold is extremely malleable and ductile as a result of which it can be converted into alloys to make minute designs which further increases its pride.
Hope this helps sorry if im wrong :c nervous.
Physics is a type of science, like life science.
Answer:
The speed is
Explanation:
From the question we are told that
The length of the rod is
The induced emf is
The magnetic field is
Generally the speed is mathematically represented as
=>
=>
We use the formula
to find the initial velocity
We have:
Initial velocity (u) = 12 m/s
Acceleration (a) = 14 m/s²
Distance (s) = 48 meters
We are looking to find the final velocity (v)
Substituting these values into the formula, we have:
v² = 12² + 2(14)(48)
v² = 144 + 1344
v² = 1488
v = √1488
v = 38.57 m/s
Answer:
The current in primary coil is 2.08 A.
Explanation:
Given that,
Power = 500 W
Voltage = 16 kV
Number of turns = 80000
We need to calculate the number of current
Using formula of voltage
Put the value into the formula
We need to calculate the current in secondary coil
Using formula of current
We need to calculate the current in primary coil
Put the value into the formula
Hence, The current in primary coil is 2.08 A.
