ii) One of the containers is wide and shallow. The other container is narrow and deep
Predict which container has the greater rate of cooling. Explain your answer.

Explanation:

for v vs t graph for t=9 to 11,v=15kmph

similarly v2=0,v3=60kmph&v4= -40kmph

Answer:

The answer is 1100kg.

Explanation:

First, you have to find the acceleration using the formula, a = (v-u)/t where v is final speed, u is initial speed and t is time :

[tex]a = \frac{v - u}{t} [/tex]

[tex]a = \frac{27 - 0}{4.5} [/tex]

[tex]a = 6m {s}^{ - 2} [/tex]

Next, you have to apply force formula, F = m×a where m is mass :

[tex]F = m \times a[/tex]

[tex]6600 = m \times 6[/tex]

[tex]m = 6600 \div 6[/tex]

[tex]m = 1100kg[/tex]

Answer:

You input potential (stored) energy into the rubber band system when you stretched the rubber band back. Because it is an elastic system, this kind of potential energy is specifically called elastic potential energy. ... When the rubber band is released, the potential energy is quickly converted to kinetic (motion) energy.

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not.

Ultraviolet Rays in the electromagnetic Spectrum Ultraviolet rays are a kind of electromagnetic radiation that extends from the visible light spectrum to the X-ray area.

Harmful rays have a long-term effect on humans, causing skin and eye problems. It is also a source of Vitamin C.

Because ultraviolet light may be absorbed by the filler substance, but not by the lamp's light. Because UV light extracts energy from the filler substance while lamp light does not,

Hence light from the ultraviolet flashlight harden the filling when light from the lamp does not.

Answer:

0.99932188871837 rounded to 2 significant figures is 1.00m or 1.0m

Explanation:

Step 1 - First calculate the force with the formula: Force = mass ×  acceleration due to gravity/ (F=mg) {g= 9.8m/s²}

4.0kg × 9.8m/s² = 39.2 Newtons

Step 2 - Then calculate the Kinectic power with the following procedure:

Kinectic force = the coefficient of Kf × mg

0.50μ × 39.2 N = 19.6 Newtons of Kinectic force

Step 3 - Use the equation for Work that is = F×d; use the value of Kf and multiply it by the given distance

W = 19.6 N × 2.0m = 39.2 Joules of energy

↓Remember that the product of Work is Energy (W=E) and that in some cases, we can set W as = kinetic energy ( [tex]\frac{1}{2}[/tex]mass×velocity²) or as = gravitational potential energy (mass *acceleration due to gravity*height)

↑Since the unknown variable that we are told to find is 'height', let's use the second formula to help us solve the problem, where we said that GPE = mgh / PEg = mgh

Step 4 - Find the missing height using the formula, Energy gained from (W = mgh), by rewriting (mgh) to solve for h

39.2 J of E = 4.0kg × (9.8 m/s² × h)

h = [tex]\frac{PEg}{mg}[/tex]

h = [tex]\frac{39.2N}{9.8m/s{2} times 4.0kg}[/tex]  

Height of box on-ramp = 1.0m

Answer: The scientific revolution began in Europe toward the end of the Renaissance period, and continued through the late 18th century, influencing the intellectual social movement known as the Enlightenment

Explanation:

Answer:

The polar coordinate of [tex]P(x,y) = (-3.50\,m,-2.50\,m)[/tex] is [tex]P (r,\theta) = (4.301\,m, 215.538^{\circ})[/tex].

Explanation:

Given a point in rectangular form, that is [tex]P(x,y) = (x,y)[/tex], its polar form is defined by:

[tex]P(x,y) = (r,\theta)[/tex] (1)

Where:

[tex]r[/tex] - Norm, measured in meters.

[tex]\theta[/tex] - Direction, measured in sexagesimal degrees.

The norm of the point is determined by Pythagorean Theorem:

[tex]r = \sqrt{x^{2}+y^{2}}[/tex] (2)

And direction is calculated by following trigonometric relation:

[tex]\theta = \tan^{-1} \frac{y}{x}[/tex] (3)

If we know that [tex]x = -3.50\,m[/tex] and [tex]y = -2.50\,m[/tex], then the components of coordinates in polar form is:

[tex]r = \sqrt{(-3.50\,m)^{2}+(-2.50\,m)^{2}}[/tex]

[tex]r \approx 4.301\,m[/tex]

Since [tex]x < 0\,m[/tex] and [tex]y < 0\,m[/tex], direction is located at 3rd Quadrant. Given that tangent function has a period of 180º, we find direction by using this formula:

[tex]\theta = 180^{\circ}+\tan^{-1} \left(\frac{-2.50\,m}{-3.50\,m} \right)[/tex]

[tex]\theta \approx 215.538^{\circ}[/tex]

The polar coordinate of [tex]P(x,y) = (-3.50\,m,-2.50\,m)[/tex] is [tex]P (r,\theta) = (4.301\,m, 215.538^{\circ})[/tex].
