Answer:
0.958891203 m/s²
Explanation:
N = Weight of crate = 900 N
= Coefficient of friction = 0.25
Force of friction acting on the force applied
Force used to pull the crate
The net force is
Acceleration is given by
The magnitude of the acceleration of the crate is 0.958891203 m/s²
Answer:
3.679 ×
Explanation:
Let's assume that average lifespan for normal human being is 70 years.
In 70 years there are 365 days in each year.
70 years = 70 × 365 days
In one day there are 24 hours.
70 years = 70 × 365 × 24 hours
In one hour there are 60 minutes.
70 years = 70 × 365 × 24 × 60 minutes
we estimate an average respiration rate of about 10 breaths per minute. ... (Given)
Thus, for 70 years number of breath are,
n = 70 × 365 × 24 × 60 × 10
n = 3.679 ×
Hence, estimate number of breath over a period of life is 3.679 × .
The balanced chemical equation is 2 AlI₃ + 3 HgCl₂ 2 AlCl₃ + 3 HgI₂ for the given chemical reaction.
<h3>What is chemical equation?</h3>
Chemical equation is a symbolic representation of a chemical reaction which is written in the form of symbols and chemical formulas.The reactants are present on the left hand side while the products are present on the right hand side.
A plus sign is present between reactants and products if they are more than one in any case and an arrow is present pointing towards the product side which indicates the direction of the reaction .There are coefficients present next to the chemical symbols and formulas .
The first chemical equation was put forth by Jean Beguin in 1615.By making use of chemical equations the direction of reaction ,state of reactants and products can be stated. In the chemical equations even the temperature to be maintained and catalyst can be mentioned.
