Answer:
chemical, mechanical, electrical
Explanation:
Answer: Option A.
Explanation:
Scientific measuring tools refers to the equipments or tools use to measure quantities in science examples include measuring cup, measuring cylinder, e.t.c.
The characteristic that describe Scientific tool is that To be accurate, it must be able to make measurements repeatedly over a long period of time because accuracy is how close the measurements for a value is to the correct value and it must take measurements for long period of time without errors.
b. Gravitational constant
Explanation:
G in the universal gravitation formula represents the gravitation constant. It's value is 2.071×10⁻⁴³ s²⋅m⁻¹⋅kg⁻¹.
- The law of universal gravitation states that "the gravitational force between two bodies is directly proportional to the product of their masses and inversely proportional to the square of the distance separating them".
Mathematically, the law is expressed as:
F = G
Where F is the gravitational force
G is the gravitational constant
r is the distance
m is the mass 1 and 2 bodies
