This is kinda confusing. I wish u just to a screenshot of the problem but here goes...

Forest at highest latitudes- Hardwood trees/deer, squirrel, foxes

Praries/temperate climate- Mostly small mammals/scrubs/steppes

High humidity/rainfall near equator- Abundant thick vegatation/manny species

No trees/ polar bears/ mosses- 25cm rain/few animals

Explanation:

When the object is placed at centre of curvature (C) of a concave mirror, a real and inverted image is formed at the same position. Properties of image: Same size of object.

Answer:

1. 50 meters

2. average velocity (?)

Explanation:

Vot + 1/2 at^2

= 0 (10) + 1/2(1)(10)^2

= 0 + 1/2 (1)(10)^2

= 1/2 (1) (100)

= 1/2 (100)

= 50

Answer:

I = 1.944 A

Explanation:

Given the following data;

Charge, Q = 3.5C

Time, t = 1.8 secs

Charge of a substance is given by the formula;

[tex] Q = It[/tex]

Where;

Q is the amount of charge measured in Colombs.

I is the current measured in Amperes.

t is the time measured in seconds.

Making I the subject of formula, we have

[tex] I = \frac {Q}{t} [/tex]

[tex] I = \frac {3.5}{1.8} [/tex]

I = 1.944 A

Therefore, the current in the circuit is 1.944 Amperes.

Answer:

The proximate answer pertaining to your question entails 10 kg.

Justification:

The statement implies which of the following units preceded by the value of 10 will obtain substantial inertia.

Exploiting conversions, this can be evinced/demonstrated:

Choice "10 m" => .01 kg

10 J ==> 0.10

10 N ==> 1.02 kg

10 kg  ==>  10 kg

Thus, an object obtaining a cumulative mass of 10 kg obtains substantial inertia.

Answer:

f= mass/acceleration

Explanation:

Answer:

The value is [tex]\lambda = 684 \ nm[/tex]

Explanation:

From the question we are told that

     The order of the dark fringe is  m  =  2

      The diffraction angle is  [tex]\theta = 20^o[/tex]

       The diffraction grating is  [tex]l = 200\ lines\ per\ mm \ = \ 200000\ lines\ per\ m[/tex]

Generally separation between the slits is mathematically represented as

        [tex]d = \frac{1}{ 200000}[/tex]

=>      [tex]d = 5 *10^{ -6} \ m[/tex]

Generally the condition for destructive interference is mathematically represented as

            [tex]dsin(\theta ) = (m - \frac{1}{2} ) \lambda[/tex]

=>    [tex]5 *10^{-6} sin(20) = [2 + \frac{1}{2}] * \lambda[/tex]

=>   [tex]\lambda = 684 *10^{-9} \ m[/tex]

=>   [tex]\lambda = 684 \ nm[/tex]

Answer:

J/kg

Explanation:

The unit of gravitational potential is J/kg.

Gravitational potential is the amount of energy needed to bring a unit mass of charge from an external point to that field.

a.  communicate the solution

Answer:

735 J

Explanation:

From the question given above, the following data were obtained:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy is simply defined as the product of weight of the object and height to which the object is raised. Mathematically, it is expressed as:

Potential energy = weight × height

With the above formula, we can obtain the potential energy of the coconut as follow:

Weight (W) = 49 N

Height (h) = 15 m

Potential energy =?

Potential energy = weight × height

Potential energy = 49 × 15

Potential energy = 735 J

Thus, the potential energy of the coconut is 735 J

Answer:

Student A is correct.

Explanation:

An electromagnet can be defined as the magnet that is produced by the electric current passing through a wire surrounding a metal piece. In an  electric motor, magnets surrounds the the coil carrying currents. Because of the magnetic field, the current carrying coil experiences a force and it starts to rotate. Thus the electric motors uses the forces between the electromagnets to start running.

Therefore, student A is correct.

Answer:

μ = 0.1

Explanation:

In order to keep the car on circular track, the centripetal force must be equal to the frictional force between tires and track:

Frictional Force = Centripetal Force

μmg = mv²/r

μ = v²/gr

where,

μ = coefficient of friction = ?

v = speed of car = 10 m/s

g = 9.8 m/s²

r = radius of track = 100 m

Therefore,

μ = (10 m/s)²/(9.8 m/s²)(100 m)

μ = 0.1

The hormonal, cardiovascular, central nervous and respiratory systems are all involved in this response.

The body is equipped to respond to emergency situations through the fight and flight hormones secreted by the adrenal gland. This chemical messengers send a message to the brain which now causes reactions such as increased pumping of blood by the heart and a faster breathing rate by the lungs.

Hence, the hormonal, cardiovascular, central nervous and respiratory systems are all involved in this response.

Ben.

Explanation:

m = Mass Bonnie and Ben lift = 50 kg

s = Displacement of mass by both the students = 0.6 m

Work done by both the student is

[tex]W=Fs\\\Rightarrow W=10\times 50\times 0.6\\\Rightarrow W=300\ \text{J}[/tex]

The amount of work done by both the students will be equal to 300 J.

[tex]t_1[/tex] = Time taken by Bonnie = 1 minute = 60 seconds

[tex]t_2[/tex] = Time taken by Ben = 10 seconds.

Power delivered by Bonnie

[tex]P=\dfrac{W}{t_1}\\\Rightarrow P=\dfrac{300}{60}\\\Rightarrow P=5\ \text{W}[/tex]

Power delivered by Ben

[tex]P=\dfrac{W}{t_2}\\\Rightarrow P=\dfrac{300}{10}\\\Rightarrow P=30\ \text{W}[/tex]

So, power delivered by Ben is more.

Answer:

[tex]a=0.125\ m/s^2[/tex]

Explanation:

Given that,

Mass of Efua, m = 40 kg

Force, F = 5 N

We need to find Efua's resulting acceleration. We know that the force acting on an object is given by :

F = ma

where a is acceleration

[tex]a=\dfrac{F}{m}\\\\a=\dfrac{5\ N}{40\ kg}\\\\a=0.125\ m/s^2[/tex]

So, the resulting acceleration is [tex]0.125\ m/s^2[/tex].

Answer:

When the person is drunk the car travels 20.1 meters more than when the person is sober. The distance traveled by car is:

Person drunk: 28.1 m

Person sober: 8 m     

Explanation:

The distance traveled can be found using the following equation:

[tex] v = \frac{x}{t} \rightarrow x = v*t [/tex]

Where:

v: is the speed = 90 km/h

t: is the time

When the person is sober, the time that takes to hit the brakes is 0.320 s, so we have:

[tex] x = v*t = 90 \frac{km}{h}*\frac{1 h}{3200 s}*0.320 s = 8 \cdot 10^{-3} km = 8 m [/tex]

And when the person is drunk, the time is 1.00 s, hence the distance is:

[tex] x = v*t = 90 \frac{km}{h}*\frac{1 h}{3200 s}*1 s = 0.0281 km = 28.1 m [/tex]

The distance traveled by the car when the person is drunk compared when the person is sober is:

[tex] d = 28.1 m - 8 m = 20.1 m [/tex]

Therefore, when the person is drunk the car travels 20.1 meters more than when the person is sober.
