Answer:
Explanation:
There is no set way to do this. All you have to do is define left and right. Left will be minus and right will be the opposite --- plus.
That is completely arbitrary. It could be the other way around. It does not matter.
Left is minus so: - 600 N is the force going left.
Right plus so: + 500 N
Now just add.
Net Force = +500 - 600
Net Force = - 100 N
So the Net Force is - 100 N going to the left.
Answer:
a)time t = 47.4s
b)speed v = 38.7cm/s
Explanation:
Given:
Total volume of blood = 4.93L × 1000cm^3/L = 4930cm^3
Volumetric rate of flow = 104.1cm^3/s
a) Time taken for all the blood to pass through the aorta is:
Time t = total volume/ volumetric rate
t = 4930/104.1
t = 47.4s
b) Given that the diameter of the aorta is 1.85cm.
V = Av
Where V = Volumetric rate
A = area of aorta
v = speed of blood
v = V/A ...1
Area of a circular aorta = πr^2 = (πd^2)/4
d = 1.85cm
A = (π×1.85^2)/4
A = 2.69cm^2
From equation 1.
v = V/A = 104.1/2.69
v = 38.7 cm/s
Answer:
P = 113.4 N
Explanation:
We know that if it is on the Moon it has another gravity. Therefore, it is known through the International System that the gravity of the Moon is 1.62 m/s², so..
Data:
- m = 70 kg
- g = 1.62 m/s²
- P = ?
Use formula:
Replace and solve:
The man's weight is <u>113.4 Newtons.</u>

Answer:
d) – 44
Explanation:
given information:
length, l = 1.2 m
diameter, d = 0.2 m
flux, Φ = -5.0 Nm/C²
ε₀ = 8.85 x 10⁻¹²
to find the net charge of the cylinder, we use the following step
Φ = E/A
= Q/ε₀
Q = Φ ε₀
= (-5.0) (8.85 x 10⁻¹²)
= - 44.25 x 10⁻¹² C
= - 44 pC (d)
