From that list, the <em>exponents</em> should be handled first.
Here's the memory device for the order of operations
that I often see here on Brainly. I didn't learn it this way,
but this is a good and handy thing to remember:
<em>P E M D A S</em>
It stands for the order in which operations should be performed
if you're working to simplify an expression that has several different
operations in it.
<em>P</em>arentheses
<em>E</em>xponents
<em>M</em>ultiplication
<em>D</em>ivision
<em>A</em>ddition
<em>S</em>ubtraction
Explanation:
It is given that,
Mass of a box car,
Initial speed of a box car,
Initial speed of another stationary car is 0 as it was stationary
Mass of another box car is 10,000 kg
Let V is the speed of the cars just after the collision. It is based on the concept of inelastic collision. So, using the conservation of linear momentum we get :
So, the speed of the cars just after the collision is 0.875 m/s.
Answer:
The correct answer is: loss of diferenciation
Explanation:
The first signals of carcinoma are those which indicate cells are changing and loosing their function. Poorly differenciated cells in a tissue are those that lack of normal features the cell must posess to perform its specific function. They usually show altered shape and size, a larger size of nucleus- even a fragmented nucleus- and the tissue look more disorganized. These kind of cells have a higher rate of division and <u>could potencially cause cancer</u>.
Answer:
0.1
Explanation:
mass, m = 5 kg
θ = 60°
Force, F = 10 N
velocity is constant , it means the net force is zero.
So, the component of force along the surface is equal to the friction force
FCosθ = friction force
10 x cos 60 = μ x m x g
where, μ is the coefficient of friction
5 = μ x 5 x 9.8
μ = 0.1
Thus, the coefficient of friction is 0.1
Answer:
38 m/s
43 m/s
Explanation:
x = 18t + 5.0t²
The instantaneous velocity is the first derivative:
v = 18 + 10.t
At t = 2.0:
v = 18 + 10.(2.0)
v = 38 m/s
The average velocity is the change in position over change in time.
v = Δx / Δt
v = [ (18t₂ + 5.0t₂²) − (18t₁ + 5.0t₁²) ] / (t₂ − t₁)
Between t = 2.0 and t = 3.0:
v = [ (18(3.0) + 5.0(3.0)²) − (18(2.0) + 5.0(2.0)²) ] / (3.0 − 2.0)
v = [ (54 + 45) − (36 + 20.) ] / 1.0
v = 99 − 56
v = 43 m/s
