Answer:Particulates are small, distinct solids suspended in a liquid or gas and example are dust,soot,and salt particles
Explanation:
Answer:
See the explanation below.
Explanation:
A species is invasive can be spread, naturally either by the behavior of the species, or introduced accidentally or voluntarily by man.
The invasive species increases its density in the occupied area or colonizes new territories over time.
That an invasive species is harmful means that it produces significant changes in the composition, structure or processes of natural or semi-natural ecosystems, endangering native biological diversity.
Uncontrolled reproduction of this invasive species also increases the risk of control and extermination of the species, due to the acclimatization of the new species in the environment as well as possible exponential reproduction.
Answer:
The net charge is
Solution:
As per the question:
Mass of the plastic bag, m = 12.0 g =
Magnitude of electric field, E =
Angle made by the string,
Now,
To calculate the net charge, Q on the ball:
Vertical component of the tension in the string,
Horizontal component of the tension in the string,
Now,
Balancing the forces in the x-direction:
(1)
Balancing the forces in the y-direction:
where
g = acceleration due to gravity =
Thus
Use T = 0.1357 N in eqn (1):
Answer:
a= 1.59 m/s² : Magnitude of the acceleration
β = 65.22° (north of east) : Direction of the acceleration
Explanation:
Conceptual analysis
We apply Newton's second law:
∑F = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Problem development
The acceleration is presented in the direction of the resultant force applied .
Calculation of the resultant forces (R)
R= 429.5 N
We apply the formula (1) to calculate the magnitude of the acceleration(a) :
∑F = m*a , m= 270 kg
R= m*a
429.5 =270*a
a= 1.59 m/s²
Calculation of the direction of the acceleration (β)
β = 65.22° (north of east)
