Scienctists agree that the world's climate is getting hotter. What do you think might happen as a result of this climate change?

Answer:

A. respiration.

Explanation:

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage.

Additionally, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

Hence, the conversion of sugar to energy in the presence of oxygen is respiration.

Answer: 0.25 m/s

Explanation:  Speed = wavelengt · frequency  

v = λf   and frequency is 1/period  f = 1/T

Then v = λ/T = 5 m / 20 s = 0.25 m/s

Answer:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti

Explanation:

The main reason for this is the engineering and technology driven building construction in Chile than in Haiti. Most of the buildings in Haiti do not fit in the building byelaws norms as most of them were constructed in a short period of time with less engineering and at cheaper rate. While building in Chile were built adhering to the building codes and byelaws.

The base of the building is Chile were separated from each other using the “base isolation” technology and the were also more flexible as compared to the buildings in Haiti.  

The skyscrapers in Chile were constructed in a way that they can float on the arrangements of ball bearings and padded cylinders

The smaller the mass of an object, the smaller its inertia, because the inertia of any object is directly proportional to the mass of the object

The ability of an object to resist changes in motion is known as inertia. The amount of inertia is directly related to an object's mass; in fact, as we frequently observe, the heavier an object is, the harder it is to change its direction of motion.

A straightforward illustration: While it is relatively simple to stop a tennis ball that has been thrown in our direction, we are aware that it is more difficult to stop a large truck that is moving in the same direction at the same speed. This is because the truck has a much higher mass than the tennis ball and a higher moment of inertia. As a result, inertia rises as mass does.

Since the inertia of any object is directly proportional to its mass, the smaller its mass, the less inertia it will have.

Answer:

t = 3 minutes

Explanation:

Given that,

Power of fan, P = 50 W

Energy used, E = 1 kWh

We know that,

Energy = Power/time

As, 50 watts = 0.05 kilowatts

So,

[tex]t=\dfrac{P}{E}\\\\t=\dfrac{0.05\ kW}{1\ kWh}\\\\t=0.05\ h[/tex]

or

t = 3 min

So, the required time is equal to 3 minutes.

Answer:

about 2.7liters for women and 3.7liters for men

Explanation:

Answer:

It follows that the magnitude in radians of one complete revolution (360 degrees) is the length of the entire circumference divided by the radius, or 2πr / r, or 2π. Thus 2π radians is equal to 360 degrees, meaning that one radian is equal to 180/π ≈ 57.295779513082320876 degrees.

Answer:

1 ohm

Explanation:

since there are two identical resistors, one resistor will be

R = [tex]\frac{4}{2}[/tex] =2ohm [ proven as in series [tex]R_{e} = 2 + 2 = 4ohm[/tex] ]

to calculate the equivalent resistance when in parallel:

[tex]\frac{1}{R_{e} } = \frac{1}{R_{1} } + \frac{1}{R_{2}}[/tex]

so,

[tex]\frac{1}{R_{e} } = \frac{1}{2} + \frac{1}{2}[/tex]

[tex]R_{e} = 1ohm[/tex]

Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

In a parallel circuit, voltage is thee same across each component in the circuit. The sum of the currents through each path is equal to the current from the source. However, the resistance cannot be added directly. It is calculated as:

1/Rt = 1/R1 + 1/R2 + 1/R3 1/Rt = 1/6.8 + 1/9.0 + 1/15

Rt = 3.08 ohms.

When resistors are connected in parallel, the equivalent resistance R will be less than the least resistance.

1/R = 1/R1 + 1/R2 + 1/R3 + 1/R4 + 1/R5

Since the 5 resistors are 10 ohms each, substitute them in to the formula

1/R = 1/10 + 1/10 +1/10 + 1/10 + 1/10

The LCM = 10

1/R = 5/10

Reciprocate both sides

R = 10/5 = 2 ohms

Therefore, Two identical resistors connected in series have an equivalent resistance of 4 ohms. The same two resistors, when connected in parallel, have an equivalent resistance of 1 ohm.

Explanation:

Given that,

The distance between masses, d = 0.5 m

We need to find the gravitational force between two large trucks. The formula for the gravitational forces is given by :

[tex]F=G\dfrac{m^2}{r^2}\\\\F=6.67\times 10^{-11}\times \dfrac{6500^2}{(0.5)^2}\\\\F=0.0112\ N[/tex]

Answer:

4.5

Explanation:

Given the following

Weight of the car = 1200N (Load)

Let us get the effort by using the formula;

F1/A1 = F2/A2

Substitute the given values

1200/0.9 = F2/0.2

Cross multiply

0.9F2 = 1200 * 0.2

0.9F2 = 240

F2 = 240/0.9

F2 = 266.67N

Hence the effort is 266.67N

Mechanical Advntage = Load/Effort

MA = 1200/266.67

MA = 4.5

Hence he mechanical advantage of the hydraulic lift is 4.5

Answer:

F = 4117.64

Explanation:

First, we will calculate the acceleration of the hand, by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration = ?

s = distance covered = compression = 8.5 cm = 0.085 m

vf = final speed = 0 m/s

vi = iniial speed = 10 m/s

Therefore,

[tex]2a(0.085\ m) = (0\ m/s)^2-(10\ m/s)^2\\a = - 588.23\ m/s^2[/tex]

negative sign hows deceleration.

Now, we will calculate the force exerted by the hand:

[tex]F = ma = (7\ kg)(588.23\ m/s^2)\\[/tex]

F = 4117.64 N

Answer:

(a) Luna

(b) Luna

Explanation:

(b)

The final speed can be found by using the third equation of motion:

[tex]2as = v_f^2 - v_i^2\\[/tex]

where,

a = acceleration

s = distance covered

vf = final speed

vi = initial speed

For Angela:

a = 2 m/s²

s = 30 m

vi = 4 m/s

vf = v_fa

therefore,

[tex]2(2\ m/s^2)(30\ m) = (v_{fa})^2 - (4\ m/s)^2\\v_{fa}^2 = 120 m^2/s^2 + 16\ m^2/s^2\\v_{fa} = 11.66\ m/s\\[/tex]

For Luna:

a = 3 m/s²

s = 30 m

vi = 3 m/s

vf = v_fl

therefore,

[tex]2(3\ m/s^2)(30\ m) = (v_{fa})^2 - (3\ m/s)^2\\v_{fa}^2 = 180 m^2/s^2 + 9\ m^2/s^2\\v_{fa} = 13.74\ m/s\\[/tex]

Therefore, Luna will be running faster at the end of the race.

(b)

To calculate the time of completion we will use the first equation of motion:

[tex]v_f = v_i + at[/tex]

FOR ANGELA:

[tex]11.66\ m/s = 4\ m/s + (2\ m/s^2)t_a\\t_a = \frac{7.66\ m/s}{2\ m/s^2}\\\\t_a = 3.83\ s[/tex]

FOR LUNA:

[tex]13.74\ m/s = 3\ m/s + (3\ m/s^2)t_l\\t_l = \frac{10.74\ m/s}{3\ m/s^2}\\\\t_l = 3.58\ s[/tex]

Hence, LUNA finishes the race first.

Answer:

It will be reflected to the principal focus of the concave mirror

Explanation:

This is because all rays parallel and close to the principal axis of a concave mirror get reflected to the principal focus of the mirror.

For a ray to be parallel to the mirror, it must be coming from an infinite distance.

So, using the mirror formula,

1/u + 1/v = 1/f where u = object distance from mirror, v =image distance form mirror and f =focal length of mirror.

Since u = infinite distance = ∞

1/u + 1/v = 1/f

1/∞ + 1/v = 1/f

0 + 1/v = 1/f

1/v = 1/f

v = f

So, the image is at the principal focus.

So, the ray of light parallel to the principal axis of the concave mirror is reflected to the principal focus of the concave mirror.
