A student who weighs 558 N climbs a stairway (vertical height of 3.3 m) in 29 s.
Answer:
Work is defined as force x displacement in the direction of the force. In this case the force is 558 N and the displacement is 3.3 m, so the work is 3.3 m x 558 N = 1,841.4 joules.
Power is work per unit of time. 1,841.4 J /29 s = 63 W.

A 53-years old lady was found by imaging to have 50% narrowing in her left renal artery. The change in blood flow for that artery is: (poiseuille Law)
A. 1⁄3 reduction in flow
B. 1⁄2 increase in flow
C. 1/16 increase in flow
D.1/16 reduction in flow
Answer:
D. 1/16 reduction in flow
Explanation:
Poiseuille's law says that the flow rate in a tube or pipe is:
[tex]Q=\frac{\pi P r^4}{8 \eta L}[/tex]
where P is the pressure difference, r is the radius, η is the viscosity, and L is the length.
Assuming that P, η, and L are constant, then we can say Q is proportional to r⁴.
Q ∝ r⁴
A 50% narrowing means the new radius is r/2. Thus the new flow is:
Q₀ / r⁴ = Q / (r/2)⁴
Q₀ / r⁴ = 16 Q / r⁴
Q = Q₀ / 16
There is a 1/16 reduction in flow.

if te steady heat flux conducted through this wall is 20 then show how one obtains the temperature distribution t(x)
The temperature distribution t(x) across a wall with steady heat flux conducted through it, t(x) = -Q/(2k) x² + (T2 - T1 + QL/2k)/L x + T1 - QL²/(4k).
To obtain the temperature distribution t(x) across a wall with steady heat flux conducted through it, we need to solve the one-dimensional heat conduction equation,
d²t(x)/dx² = -Q/k
Where t(x) is the temperature at position x, Q is the steady heat flux conducted through the wall, and k is the thermal conductivity of the wall material.
t(x) = -Q/(2k) x² + Ax + B
Boundary conditions,
t(0) = T1 and t(L) = T2
Where T1 and T2 are the temperatures at the two ends of the wall, and L is the length of the wall.
Using these boundary conditions,
A = (T2 - T1 + QL/2k)/L
B = T1 - QL²/(4k)
Substituting these values of A and B in the equation for t(x),

What is the airspeed of a plane relative to the ground?The air speed of a flying airplane relative to (a specified location on) the ground is the difference between the airplane's ground speed and the speed of the wind, found using vectors as follows;
Mathematically, we get;
Airspeed = Ground Speed - Wind SpeedWhereby the velocity of the wind is 120 m/s and the airplane is traveling with an airspeed of 300 m/s due east for example, and the airplane travels 80 meters east and 20 meters south relative to the ground in one second, we get;

A student throws a 0.140-kg ball straight upwards to a height of 3.10 m. How much work did the student do?
Answer:
The student did 4.54 joules of work. This can be determined by using the formula W = mgh, where W is the work done, m is the mass of the ball, g is the acceleration due to gravity, and h is the height to which the ball is thrown. In this case, m = 0.140 kg and h = 3.10 m, so W = 0.140 x 9.8 x 3.10 = 4.54 joules.
What is the acceleration of a 2,500-kg single-engine airplane just before takeoff when the thrust of its engine is 500N?
The acceleration of a 2,500-kg single-engine airplane just before takeoff when the thrust of its engine is 500N is, 0.2 m/s²
What is acceleration ?Acceleration is a vector quantity that describes the rate at which an object changes its velocity. It is the rate at which the velocity of an object changes in magnitude or direction, or both. In other words, it tells us how quickly an object is speeding up or slowing down. Acceleration has units of meter per second squared (m/s²) and its direction is the same as the direction of the change in velocity.
The net force acting on the airplane just before takeoff is equal to the thrust of the engine,
which is 500 N, minus the force of drag.
Since the airplane is just about to take off, the force of drag is relatively small,
So we can assume that the net force is equal to the thrust of the engine.
F = m x a
Where F is the net force, m is the mass, and a is the acceleration.
Substituting the values for F and m, we get:
500 N = 2,500 kg x a
Dividing both sides by 2,500 kg, we get:
a = 500 N / 2,500 kg = 0.2 m/s²
So, the acceleration of the 2,500-kg single-engine airplane just before takeoff when the thrust of its engine is 500 N is 0.2 m/s².

If a force of 160 ± 6 N is applied to an area of 24 ± 3 cm², determine the pressure and the uncertainty in its calculation?
Answer:
Explanation:
The pressure is calculated by dividing the force by the area:
P = F / A = 160 N / 24 cm² = 6.67 N/cm²
The uncertainty in the calculation of pressure can be determined by propagating the uncertainties in the force and area measurements. According to the formula for uncertainty propagation, the fractional uncertainty in the pressure calculation is:
ΔP / P = √((ΔF / F)^2 + (ΔA / A)^2)
Plugging in the values:
ΔP / P = √((6 N / 160 N)^2 + (3 cm² / 24 cm²)^2)
ΔP / P = √(0.0375) = 0.195
So the fractional uncertainty in the pressure calculation is 0.195 or 19.5%.
To find the absolute uncertainty in the pressure, multiply the fractional uncertainty by the pressure:
ΔP = P * ΔP / P = 6.67 N/cm² * 0.195 = 1.29 N/cm²
So, the pressure is 6.67 ± 1.29 N/cm².

When two objects are suspended from threads, the movement of one object close to the other can cause the electrons in the atoms of one object to be transferred to the other, resulting in one object gaining a positive charge and the other gaining a negative charge.
This causes the two objects to attract each other due to the opposite charges.
This phenomenon is known as electrostatic attraction, and it occurs due to the electrostatic force of attraction between charged objects.

Answer:
Explanation:
Centripetal acceleration is the acceleration that points towards the center of a circular path and is responsible for keeping an object moving in a circular path. The equation for centripetal acceleration is:
a_centripetal = v^2 / r
where v is the speed of the object and r is the radius of the circular path.
Centripetal force is the force that acts on an object moving in a circular path and is directed towards the center of the circular path. It is equal to the product of the mass of the object and its centripetal acceleration. The equation for centripetal force is:
F_centripetal = m * a_centripetal

(c) How long does the car take to stop completely in seconds?
(d) What distance does the car travel in this time in meters?
(e) What was the car’s initial speed in m/s?
The angular acceleration of its tires is 26.23 rad/s².
The number of revolutions is by the tire is 24.57 rev.
The time it takes the car to stop is 48.2 s.
The distance of the car will be calculated in d = v0 × t + (1/2) × a × t²
And the car's initial speed in v0.
How to calculate angular acceleration?a) The formula for angular acceleration (α) can be calculated as α = r/a, where r is the radius of the tire and a is the linear acceleration. So, in this case, α = 0.26 / 7.6 = 26.23 rad/s².
b) The formula for angular velocity (ω) at a given time can be calculated as ω = ω0 + αt or ω² = ω²0 + 2αΔΘ , where ω0 is the initial angular velocity and t is the time. To find the number of revolutions, find the time it takes for the angular velocity to reach 0. The equation would be 0 = 95 + 1.97t. ω²= 2 x 26.23ΔΘ. = 9025 = 58.46ΔΘ
ΔΘ = 9025 / 58.46 = 154.375 rad. n = ωt / (2π). = 154.375/2π = 24.57 rev.
c) We can find the time it takes for the tires to come to rest by solving for t in the equation 0 = 95 + 1.97t. So, t = 95 / 1.97 = 48.2 s.
d) The distance traveled by the car can be calculated as d = v0 × t + (1/2) × a × t^2, where v0 is the initial speed and a is the linear acceleration. However, as the initial speed is not given, the distance cannot be determined.
