A 0.50-kg ball is thrown vertically upward with an initial velocity of 35 m/s. Approximately, how high will the ball rise?

Answer:

D. Tidal energy is replaced naturally by the Moon's gravity.

Explanation:

The reason tidal energy is considered a renewable energy resource is that Tidal energy is replaced naturally by the Moon's gravity. The Moon's gravity creates bulges on the side of Earth that is closest and farthest from the Moon. These bulges also pull water causing high tides in those areas. As the Earth rotates these areas experience low tide while the areas that had low tide now experience high tide. This constant shift creates tidal energy every day, which is replenished naturally.

Using Newton's law of cooling, the time of death could have been 2 hours and 7 minutes before the body was found or around 9:53 AM.

According to Newton's Law of Cooling, the change in temperature of a body is proportional to the difference between its own temperature and the temperature of its surroundings. The law is expressed by the formula:

T(t) = T_a + (T_0 - T_a)e^(-kt),

where T(t) is the temperature of the body at time t, T_0 is the initial temperature of the body, T_a is the ambient temperature (in this case, 65 degrees Fahrenheit), and k is a constant of proportionality.

To find the time of death, we need to solve for t in the formula above. We know that at the time of death, the body temperature was 98.6 degrees Fahrenheit, so T_0 = 98.6. We also know that two hours later, the core temperature had fallen to 88 degrees Fahrenheit, so T(2) = 88. Plugging these values into the formula, we get:

88 = 65 + (98.6 - 65)e^(-k*2)

23 = 33.6e^(-2k)

ln(23/33.6) = -2k

0.3257 = k

Now we can solve for t using the formula:

T(t) = 65 + (98.6 - 65)e^(-0.3257t)

We want to find the time when the body temperature was 98.6 degrees Fahrenheit, so we plug that value in for T(t) and solve for t:

98.6 = 65 + (98.6 - 65)e^(-0.3257t)

33.6 = 33.6e^(-0.3257t)

e^(-0.3257t) = 1

t = ln(1)/(-0.3257)

t = 2.12 ≈ 2 hours and 7 minutes

Therefore, the time of death was about 2 hours and 7 minutes before the body was found or at around 9:53 AM.

1. The maximum displacement of the gram-negative bacterium during a 1-hour period, moving at a constant speed of 25 µm/s, would be 90 mm.

2. Assuming the Spring constant to be 1. The work done when the spring length is increased from 20 cm to 30 cm, is 0.5 J.

The bacterium's constant speed of 25 µm/s can be converted to mm/s by dividing by 1000, which gives us 0.025 mm/s. To find the maximum displacement, we multiply the speed by the time. In this case, the time is 1 hour, which is equivalent to 3600 seconds. Multiplying 0.025 mm/s by 3600 seconds gives us 90 mm. Therefore, the maximum displacement of the bacterium during a 1-hour period would be 90 mm.

The formula for calculating work done is given by \(W=\frac{1}{2} *k*(x_2^2-x_1^2)\), where W is the work done, k is the spring constant, \(x_2\) is the final length, and \(x_1\) is the initial length of the spring. In this case, the spring constant is 1, \(x_2\) is 30 cm (or 0.3 m), and \(x_1\) is 20 cm (or 0.2 m).

Substituting the values into the formula, we have W = (0.5)(1)(0.09- 0.04). Simplifying the equation, we get W = 0.025 J.

Therefore, the work done when the spring length is increased from 20 cm to 30 cm, with a spring constant of 1, is 0.025 J or 0.5 J when rounded to two decimal places.

so:

43560ft²= 0.09290304m²×43560

= 4,046.8564224 m²

Answer: 4046.9m² (approx.)

Explanation:

An acre is 43560 ft², but the US has two feet, the International foot, and the (old) Survey foot. Since 1983, the answer varies by state according to which foot the State has adopted for surveying. (Previously, it was always the Survey foot).

International: 43560 ft² x (0.3048 m/ft)² = 4046.856 422 m²

Survey: 43560 ft² x (1200/3937 m)² = 4046.872 610 m²

Both round to 4046.9 m² if that’s good enough, but there is a tiny difference.

Explanation:

The car will travel a distance of 180 meters in 12 seconds.

To determine the distance traveled by the car, we can use the equation of motion:

Distance (d) = Initial velocity (v₀) × time (t) + 0.5 × acceleration (a) × time squared (t²)

Given:

Initial velocity (v₀) = 0 m/s (starting from rest)

Acceleration (a) = 2.5 m/s²

Time (t) = 12 seconds

Plugging in the values into the equation:

Distance (d) = 0 × 12 + 0.5 × 2.5 × 12²

Distance (d) = 0 + 0.5 × 2.5 × 144

Distance (d) = 0 + 0.5 × 2.5 × 144

Distance (d) = 180 meters

Prima facie means the evidence is valid on its face, or based on the evidence, and the elements.

Prima facie, a Latin phrase that means "at first glance" or "based on first impression," The feminine versions of primus, which means "first," and facies, which means "face," both in the ablative case, would be translated literally as "at first face" or "at first appearance." "On the face of it" is a typical translation in contemporary, colloquial, and conversational English.

Prima facie refers to the initial appearance of enough supporting evidence to establish a case, and it is used in modern legal English (both in civil law and criminal law). Prima facie evidence is a term used in common law regimes to describe evidence that, absent rebuttal, would be sufficient to establish a certain claim or fact.

The tension in the rope at the midpoint of the high wire is 76.4 N.

To determine the tension in the rope, we need to use the concept of forces and equilibrium. At the midpoint of the rope, the weight of Arlene acts downwards and the tension in the rope acts upwards.

The first step is to find the weight of Arlene, which is given by the product of her mass and the acceleration due to gravity (g) on the earth's surface, i.e.,

Weight = mass x g = (45.0 kg) x (\(9.81 m/s^2\)) = 441.45 N

Next, we need to resolve this weight force into its components along the rope and perpendicular to the rope.

The component of the weight force along the rope is given by Wsinθ, where θ is the angle of sag, i.e.,

Wsinθ = (441.45 N) x sin(10.0°) = 76.4 N

Therefore, the tension in the rope is equal to the weight force component along the rope, i.e.,

Tension = Wsinθ = 76.4 N

So, the tension in the rope at the midpoint is 76.4 N.

A ball is traveling at a constant speed of 8.5 m/s in a circle with a radius of 0.8 m;the centripetal acceleration of the ball is 90.3125 m/s²

To find the centripetal acceleration of a ball traveling at a constant speed of 8.5 m/s in a circle with a radius of 0.8 m, you can use the formula:
Centripetal acceleration (a_c) = (constant speed)² / radius
Step 1: Plug in the given values.
a_c = (8.5 m/s)² / 0.8 m
Step 2: Square the constant speed.
a_c = 72.25 m²/s² / 0.8 m
Step 3: Divide the squared speed by the radius.
a_c = 90.3125 m/s²

Answer:

runway length  = 1,867.78 meters

Explanation:

This problem can be solved using equation of motion

\(v^2 = u^2 + \ 2as\)

where

v is the final velocity

u is the initial velocity and

s is the distance a body moved to reach speed equal to final velocity .

__________________________________

Given

a = 1.8 m/s2

u is the initial velocity which will be zero as the plane starts on the ground at that point speed is zero

Let S be the distance taken to reach speed 82 m/s at acceleration of 1.8 m/s^2

This , distance will be the length of runway as well.

v = 82 m/s

using the equation of motion

\(v^2 = u^2 + \ 2as\\=> 82^2 = 0^2 + \ 2*1.8*S\\=> 6724 = 0 + 3.6 S\\=> S = 6724/3.6 = 1,867. 78\)

Thus, distance is 1,867.78 meters,

Hence , we can say that runway length should be 1,867.78 meters so that when plane lifts off its speed is 82 m/s.

Increasing capillary pressure causes edoema, whereas decreasing it encourages the reabsorption of fluid from the interstitial space into the blood. Capillary pressure favours the filtration of fluid into the interstitial space.

When blood is removed from the body in large amounts through the capillaries' apertures, filtering takes place. Reabsorption, on the other hand, happens at the venous end of the capillary when fluid is transferred by bulk flow in the reverse direction, back into the blood.

To distinguish it from capillary colloid osmotic pressure, capillary blood pressure is also sometimes referred to as capillary hydrostatic pressure. Only exposed organs with thin tissues (such a mesentery) that allow for effective transillumination can be used to record PC. With a fine micropipette (tip diameter 5 m) loaded with saline and heparin, one impales the capillary lumen. A manometer, which has a sidearm that connects to a syringe, is connected to the micropipette lumen. Blood starts to slowly ascend the pipette following the impalement. Since pipette pressure is less than PC at this moment, any pressure reading would be understated.
