To find the value of w that will result in a maximum tensile bending stress of 3 ksi, we first need to determine the moment of inertia of the cross-sectional shape of the material in question. Once we have this value, we can use the following formula to calculate the maximum tensile bending stress:

σ = M*c/I

Where σ is the maximum tensile bending stress, M is the bending moment, c is the distance from the neutral axis to the outermost fiber, and I is the moment of inertia.

Assuming that the bending moment is known, we can rearrange the formula to solve for the required value of w:

w = (M*c)/(I*σ)

This will give us the required width of the material to ensure that the maximum tensile bending stress does not exceed 3 ksi. Please note that this is a long answer that requires additional information about the material and the conditions under which it will be used.

Answer: 5 m/s North

Explanation:

Velocity = Momentum/Mass

Velocity = 225 kg*m/s/45kg

Velocity = 5 m/s North

False. Hydrostatic pressure force does not always act on the centroid of the area.

The statement that hydrostatic pressure force always acts on the centroid of the area is false. Hydrostatic pressure is the pressure exerted by a fluid at rest due to the weight of the fluid above it. It depends on the depth and density of the fluid and is perpendicular to any surface it acts upon.

When considering a submerged surface, such as a submerged plate or wall, the hydrostatic pressure force is indeed applied normal to the surface. However, this force does not necessarily act at the centroid of the area. The distribution of hydrostatic pressure forces depends on the shape and orientation of the surface.

For irregularly shaped surfaces or surfaces with varying depths, the hydrostatic pressure force acts differently at different points. It follows the principle of Pascal's law, which states that the pressure at a point in a fluid is transmitted equally in all directions. As a result, the force distribution can vary across the surface.

In summary, the hydrostatic pressure force does not always act on the centroid of the area. Its distribution depends on the shape, orientation, and depth of the submerged surface, following the principles of Pascal's law.

The incorrect statement is a. The ball does not accelerate in the horizontal direction.

When the ball is projected horizontally, it moves forward with a constant horizontal velocity. This means that it does not accelerate in the horizontal direction, so statement a is incorrect. However, in the vertical direction, the ball is subject to the force of gravity, which causes it to accelerate downwards at a rate of 9.8 m/s^2. This means that the ball's vertical velocity changes by 9.8 m/s each second. When the ball hits the ground, it has both a horizontal and vertical velocity, so statement c is also incorrect.

To solve this problem, we need to use the kinematic equations of motion to determine the hang time of the Cuban tree frog during a single jump.

What is Velocity?

It is defined as the displacement of an object per unit time in a particular direction.

In other words, velocity is the speed of an object in a given direction. It is a vector quantity because it has both magnitude (the speed) and direction.

First, we need to find the vertical component of the initial velocity vector (v0) using the sine function:

sin(26°) = vy / 4.5 m/s

vy = 4.5 m/s sin(26°) = 1.98 m/s

The vertical component of the velocity vector determines how high the frog will jump.

Next, we can use the following kinematic equation to solve for the hang time (t) of the frog:

Δy = v0yt - 1/2 gt^2

where Δy is the vertical displacement (i.e., how high the frog jumps), v0y is the vertical component of the initial velocity vector, g is the acceleration due to gravity (9.8 m/s^2), and t is the hang time.

Since the frog jumps on level ground, its vertical displacement is zero (i.e., it returns to its original height). Therefore, we can simplify the equation as follows:

0 = v0yt - 1/2 gt^2

t(1/2 g t - v0y) = 0

t = 0 or t = 2v0y / g

We can discard the solution t = 0 because it is not physically meaningful. Therefore, the hang time of the Cuban tree frog during a single jump is:

t = 2v0y / g = 2(1.98 m/s) / 9.8 m/s^2 = 0.40 s

Therefore, the answer is (d) 0.40 s.

The smallest angular size that this telescope could resolve would be determined by the blurring effects of the Earth's atmosphere.

An object's apparent size as observed from an observer on Earth is referred to as its angular size. Since telescopes gather and magnify light from far-off objects, the magnitude of lights gathered, which could be altered by fuzzy earth atmosphere, can have an impact on the least angular size. Astronomical observations are severely constrained by Earth's atmosphere for two main reasons.

First, not all wavelengths in the atmosphere are equally transparent, and some wavelength regimes are completely unreachable from the ground. Therefore, the earth's atmosphere must be taken into account while designing a telescope with a given angular size.

The correct option to the potential measured against the CSE reference electrode is (D) -95 mV CSE.

The correct option is (D) -95 mV CSE.

To convert -150 mV SCE (standard hydrogen electrode) to the potential measured against a CSE (copper sulfate electrode) reference electrode, you can use the following equation:

\(E(CSE) = E(SCE) + E\°(SCE/CSE)\)

where E(CSE) is the potential measured against the CSE reference electrode, E(SCE) is the potential measured against the SCE reference electrode, and E°(SCE/CSE) is the standard potential for the SCE/CSE half-cell, which is 0.78 volts.

Substituting the given values into the equation:

\(E(CSE) = -150 mV + 0.78 V\\E(CSE) = 0.63 V\)

Therefore, the potential measured against the CSE reference electrode is 0.63 volts, which is equivalent to (D) -95 mV CSE.

a) The tangential speed of the ball is 1.26 m/s

b) The centripetal acceleration of the ball is 1.99 m/s^2.

We need to use the formulas for tangential speed and centripetal acceleration:

Tangential speed = radius x angular speed

Centripetal acceleration = (tangential speed)^2 / radius

Given:

Mass of the ball, m = 5.00 kg

Radius of the circle, r = 0.800 m

Angular speed, ω = 0.500 rev/s

We need to convert the angular speed from revolutions per second to radians per second:

ω = 0.500 rev/s x 2π rad/rev = 1.57 rad/s

(a) Tangential speed of the ball:

v = rω = 0.800 m x 1.57 rad/s = 1.26 m/s

To solve this problem we must use Newton's second law which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

∑F = m*a

where:

F = force [N]

m = mass = 87 [kg]

a = acceleration [m/s²]

The frictional force will be taken as negative, since it opposes the movement of the block.

Complete question is;

Li and Raj are playing football. They take turns trying to run past each other with the football. Li weighs 125 pound and Raj weighs 175 pounds. Li discovers that if he changes direction quickly when running, he can always dodge out of the way before Raj can tackle him.

Why is Li able to avoid Raj’s tackle? Choose the best description.

A) Raj has more mass and therefore more inertia, so he can change his motion more easily than Li.

B) Raj has more mass and therefore less inertia, so he can change his motion more easily than Li.

C) Li has less mass and therefore more inertia, so he can change his motion more easily than Raj.

D) Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.

Answer:

Option D - Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.

Explanation:

From Newton's first law of motion which is known as law of inertia, an object will remain at rest or continue in constant motion unless an external force acts upon it. This means that Inertia is simply the resistance of an object to any change in its state of rest or motion.

This means that the larger the mass of the object, the more resistance the object will have from an external force. Similarly, the smaller the object, the less resistance it will have from an external force.

Therefore, we can see that larger mass means larger resistance and in turn larger inertia while smaller mass denotes smaller resistance and in turn smaller inertia.

Now, from the question,Li weighs 125 pound and Raj weighs 175 pounds. So, Li has lesser mass than Raj, and so he also has less inertia. Thus, he can change his motion more easily than Raj due to that.

Answer:

Li has less mass and therefore less inertia, so he can change his motion more easily than Raj.
