Explanation:
A student solving for the acceleration of an object has applied appropriate physics principles and obtained the expression as :
.............(!)
Where
m = 7 kg
We need to find the value of a from equation (1). On solving we get :
Hence, this is the required solution.
60 minutes = 1h
500/x = 10/100

The first transistor made of gold, plastic and germanium was about the size of adult's fingernail.
Option C
<u>Explanation:</u>
The first transistor made of gold, plastic and germanium was invented in Bell laboratories. It is termed as point contact transistor. As it is made like a pointed arrow with both the sides covered with layer of gold foil. The germanium is used at the tip, just like the base and the gold foil ends as collector and emitter.
The size of this transistor is about the size of adult's fingernail. It is very small in size and it was one of its kind. Due to this small size and the working capacity by the point contact, it is termed as point contact transistor.
We know, a = v₂ - v₁ / t
Here, (v₂-v₁) = 33 - 11 = 22 m/s
t = 10 s
Substitute their values,
a = 22/10
a = 2.2 m/s²
In short, Your Answer would be 2.2 m/s²
Hope this helps!
Answer:
A
Explanation:
Iron and gadlinium are both very easily made into magnetic substances. Cobalt is also capable of being magnetized. Aluminum, put in an alloy, can make a magnetic substance, but
Aluminum by itself is not able to be magnetized.
