0.7 mL of HEPARIN 10,000 units/mL is needed for a 7,000 unit dose.
To calculate the volume of HEPARIN 10,000 units/mL needed for a 7,000 unit dose, we can use the formula:
Volume (mL) = Dose (units) / Concentration (units/mL)
Given that the dose is 7,000 units and the concentration of HEPARIN is 10,000 units/mL, we can plug these values into the formula:
Volume (mL) = 7,000 units / 10,000 units/mL
Volume (mL) = 0.7 mL
So, 0.7 mL of HEPARIN 10,000 units/mL is needed for a 7,000 unit dose. However, none of the provided answer choices match exactly with 0.7 mL. The closest option is B. 0.07 mL, which is one-tenth of 0.7 mL. Therefore, the correct answer is B. 0.07 mL.

A solid sphere and a solid cylinder , both uniform and having the same mass and radius, are released from rest at the same height on a ramp. If they roll down the ramp without slipping, which one will have the lower forward velocity at the bottom of the ramp?
a. The solid sphere
b. The solid cylinder
c. Both will have the same forward velocity
Answer:
I (cylinder) = 1/2 M R^2
I (sphere) = 2/5 M R^2
The equation of motion shows
I * alpha = M g R sin theta = const
An increase in the moment of inertia will result in a smaller acceleration
The cylinder will have the smallest forward velocity because it will arrive at the bottom after the sphere
Diamond has a density of 3.26 g/cm3
. What
is the mass of a diamond that has a volume of
0.214 cm3
?
Answer in units of g
Explanation:
Hey there!
According to the question;
Density of diamond (d) = 3.26g/cm³
And Volume (v) = 0.214 cm³
Mass(m) = ?
From the definition of density;
d = m/v
Or, 3.26 g/cm³ = m/(0.214 cm³)
or, 3.26 g/cm³ * 0.214 cm³ = m
Therefore, mass of the diamond is 0.69764 g.

How to use calculus in physics ?
Explanation:
In Physics, many quanitties are the function of other quanitities.
For instance in kinematics, where the displacement (s), position (x), velocity (v) and time (t) of a particle are related.
Suppose the position of a particle can be descirbed as a function of time, i.e.
[tex]x=f(t)[/tex]
then since velocity is the rate of change of position, we write
[tex]v=\dfrac{d}{dt}f(t)=f'(t)[/tex]
which is the derivative of the poisiton/ time function.
On the other hand, the displacement of the particle is the sum of position changes over time, so the displacement can be defined by
[tex]s=\int^{t_1}_{t_0}f(t)dt[/tex]
which is the integration of postion/ time function.

Prove that s=ut+½at²
Explanation:
Distance travelled = Area under the line
= ut + ½ (v-u)t
Acceleration (a) = (v-u)/t and so (v-u) = at
Therefore,
Distance travelled (s) = ut + ½ (v-u)t = ut + ½ (at)t = ut + ½ at²
Thus,proved.

Velocity problem 3: How far away can you run away from a lion if you travel at 3 m/s west and
you have only 15 seconds?
Answer Explanation:

You will be 3(15) = 45 m west of where you began.
As we do not know where the lion is to begin with, it's hard to say where we will end up relative to it.
A lad, waiting for his friend walks in the sidewalk, in front of her house, from the front door, first, he moves towards the Positive x-axis, 5 m, then goes back, 6 m. What is his total displacement from his original position? Displacement is a vector quantity whilst, distance is a scalar quantity.
His total displacement from his original position is -1 m
We know that total displacement of an object from a position x to a position x', d = final position - initial position.
d = x' - x
If we assume the lad's initial position in front of her house is x = 0 m. The lad then moves towards the positive x-axis, 5 m. He then ends up at x' = 5 m. He then finally goes back 6 m.
Since displacement = final position - initial position, and his displacement is d' = -6 m (since he moves in the negative x - direction or moves back) from his initial position of x' = 5 m.
His final position, x" after moving back 6 m is gotten from
x" - x' = -6 m
x" = -6 + x'
x" = -6 + 5
x" = -1 m
Thus, his total displacement from his original position is
d = final position - initial position
d = x" - x
d = -1 m - 0 m
d = -1 m
So, his total displacement from his original position is -1 m

Vector A has a magnitude of 75.0 cm and points at 30° above the positive x-axis. Vector B has a magnitude of 25.0 cm and points along the negative x-axis. Vector C⃗ has a magnitude of 40.0 cm and points at 45° below the negative x-axis.
(a) Determine the x and y components of Vector A
(b) Determine the x and y components of Vector B .
(c) Determine the x and y components of Vector C .
(d) Determine x and y components of the sum of these three vectors.
(e) Determine the magnitude of the sum of these three vectors.
(f) Determine the direction of the sum of these three vectors.
(a)
A = (75.0 cm) (cos(30°) i + sin(30°) j)
A = (75.0 cm) (√3/2 i + 1/2 j)
A ≈ (64.95 i + 37.5 j) cm
The x component is the coefficient of the i unit vector, while the y component is the coefficient of the j unit vector.
(b) "points along the negative axis" in other words means that B makes an angle of 180° with the positive x-axis in the counterclockwise direction. In particular this tells you that B is parallel to the x-axis, so its y component would be zero.
B = (25.0 cm) (cos(180°) i + sin(180°) j)
B = (25.0 cm) (-1 i + 0 j)
B = (-25.0 i) cm
(c) If the negative x-axis corresponds to 180°, then 45° below this would make an angle of 180° + 45° = 225° with the positive x-axis.
C = (40.0 cm) (cos(225°) i + sin(225°) j)
C = (40.0 cm) (-1/√2 i - 1/√2 j)
C ≈ (-28.28 i - 28.28 j) cm
(d) The sum A + B + C has components that are the sums of the components of each of A, B, and C.
A + B + C ≈ (11.67 i + 9.22 j) cm
(e) The magnitude of the vector sum is
||A + B + C|| = √((11.67 cm)² + (9.22 cm)²) ≈ 14.87 cm
(f) Since both components of the vector sum are positive, you know that it's a vector that terminates in the first quadrant of the x,y-plane, so it makes an angle with the positive x-axis of
arctan(9.22/11.67) ≈ 38.3°

A rock is thrown straight up from the edge of a cliff. The rock reaches the maximum height of 15 m above the edge and then falls down to the bottom of the cliff 35 m below the cliff. What is the traveled distance of the rock?
A. 30 m B. 35 m C. 50 m D. 65 m
Answer:
The distance travelled by the rock is 65m
The rock is thrown 15 m up from the edge of the cliff and it have to travel 15 m down to reach the cliff and go to bottom of the cliff by 35 m. Thus, the total distance travelled by the rock is 65 m.
What is distance?Distance is a physical quantity used to measure how far an object is travelling. It is a scalar quantity and is characterised by magnitude only. Distance travelled is sometimes substituted with displacement. Both have the units in cm, m, feet, kilometer etc.
Distance in physics is the product of the speed of a moving body and the time taken complete the travel.
Distance = speed × time.
It is given that, the rock is thrown straight up from the edge of a cliff and it reaches upto 15 m. Then it have to return back this 15 m down to reach the edge. From there it goes 35 m below.
Thus, total distance = 15 + 15 + 35 = 65 m.
Therefore, the total distance travelled by the rock is 65 m.

g A high-energy photon turns into and electron and a positron. (A positron has exactly the same mass as the electron, but opposite charge.) What is the longest wavelength that the photon can have for this process to occur
Answer:
2 m = E / c^2 where m is mass of electron
E = h v where v is the frequency ( nu) of the incident photon
E = h c / y where y is the incident wavelength (lambda)
2 m = h / (c y)
y = h / (2 m c) wavelength required
y = 6.62 * 10E-34 / (2 * 9.1 * 10E-31 * 3 * 10E8) m
