Answer:
Answer; v= 1.2654m/s
T= 110.76N
Explanation:
Apply Momentum Principle
Fdtro - Mgridt = Iow +Mvr
Fdtro - Mgridt = mK2 v/r1 + Mvr1
85 x 3x 0.345 -11 x 9.81 x 0.23 x 3 =30 x 0.25 x 0.25 x v/0.23 + 11 x v x 0.23 =
v = 1.2654m/s
To find the timed average value
Tdt -Mgdt =MV
T x 3 - 11 x 9.81 x 3 = 11 x 0.778
T= 110.76N
Answer:
<h2>13N</h2>
Explanation:
<em>Kindly see attached file for your reference</em>
Step one:
given data
the horizontal component of the force= 12N
the vertical component of the force= 5N
The dashed arrow represents the hypotenuse of the triangle, hence the resultant of the force system.
By implication of this, we will use the Pythagoras theorem to solve for the resultant force
Step two:
An example for ruining a biodiversity is fishing.
The two factors that have
contributed to increased fishing in deep ocean waters in recent years are the
human population growth and decreased fishing opportunities inshore. Increase
population growth increases the demand for food which also leads to increase in
fish demand. Because the fish demand is high, inshore fishing opportunities
decrease that is why deep ocean waters is the new venue for fishing. This may sound absurd but poaching for subsistence is likely to be less damaging to he biodiversity <span>of an area than poaching for profit. Because the people do not care anymore to the biodiversity that they interrupted just to get back more profit. They do not care what must be taken from it like getting bigger fishes and leaving the smaller ones behind to maintain productivity.</span>
Answer:
They are rechargeable
They have a longer life span
They are reusable
Explanation:
Lead acid accumulators and leclanche cells are types of electrochemical cells.
Leclanche cells are primary cells. Primary cells produce chemical reactions through which the electric current generated is irreversible.
Lead Acid Accumulators are secondary cells in which electric current generated is reversible.
This makes lead acid accumulators reusable, more durable and they have a longer life span.
Answer:
Change in kinetic energy is ( 26CL³)/3
Explanation:
Given :
Net force applied, F(x) = Cx² ....(1)
Displacement of the particle from xi = L to xf = 3L.
The work-energy theorem states that change in kinetic energy of the particle is equal to the net amount of work is done to displace the particle.
That is,
ΔK = W = ∫F·dx
Substitute equation (1) in the above equation.
ΔK = ∫Cx²dx
The limit of integration from xi = L to xf = 3L, so
Substitute the values of xi and xf in the above equation.
