Help me I do not understand

My answer is "Watt per square meter".

Answer:

a = F/m

Explanation:

So we have to isolate a, in order to do this we need to move m to the other side, and we do that by diving both sides by m, resulting in a = F/m

Answer:

The answer to the question is 90 cm i.e the object distance is 90 cm from the mirror.

CALCULATION:

As per the question, the focal length of the convex mirror f = 30 cm.

The magnification is: 1/4

We are asked to calculate the object distance [u].

As per the sign convention for reflection, the measurements taken along the direction of light is taken as positive and its reverse is taken as negative.

The transverse measurement above the principal axis is taken as positive and below the principal axis is taken as negative.

Hence, the focal length of the convex mirror f = +30 cm.

The image formed by a convex mirror is virtual and erect.

Hence, the magnification will be positive.

Hence, magnification m = +1/4=+0.25

The relation between focal length, magnification and object distance is given as -

m=  f/f=u

u=  m=1/m multiplyed by f

=  0.25=1/0.25 multiplyed by -(30)

=  -90 cm [ans]

   Here, the negative sign is due to the fact  that object distance is measured opposite to the direction of  light.  

(sorry, brainly didn't allow me to put pictures of the calculation)

hope this helps :)

[tex] \boxed{ \boxed{ \sf{see \: below}}}[/tex]

Explanation:

[tex] \underline{ \bold{ \underline{ \huge{ \boxed{ \sf{gravitational \: force}}}}}}[/tex]

------------------------------------------------------------------

According to Newton, the bodies in the universe attract each other. This force if attraction is called force of gravitation. For example, the earth attracts the moon and the moon attracts the earth too. Similarly, the earth attracts the Jupiter and the Jupiter attracts the Earth.

The effect of force of attraction of a big body on a small body can be observed but that of a small body on a big one cannot be observed. The sun is so large that even the sum of the masses of all its planets and the satellites is only about 0.0015th part of mass of the sun. Due to the gravitational force between the sun and the earth, the earth keeps on moving around the sun. Similarly, the gravitational force between the satellites and planets makes the satellites to revolve around the planets. So, The gravitational force is responsible for the existence of solar system. The effect of gravitation can be experienced more on liquid than solid. Hence, we see tides in the sea and ocean due to the force of gravitation of the moon and the sun on the earth when they lie on the same straight line.

[tex]\huge\boxed{Radiation}[/tex]

Explanation:

In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".

Answer:

[tex]\huge \boxed{\mathrm{\bold{C.} \ Radiation}}[/tex]

Explanation:

Microwaves heat food through the form of waves.

The waves are electromagnetic waves that transfer heat through the process of radiation.

Answer:

Your microwave will not turn on, and you speculate that a circuit breaker in the house has been tripped. In scientific terminology, the steps would be described as: developing a hypothesis based on an observation.

Answer:

t = 20 s

Explanation:

145 m = 9 m/s × t – 35m

We can obtain the value of t in seconds by doing the following:

145 m = 9 m/s × t – 35m

Add 35 m to both side as shown below:

145 m + 35 m = 9 m/s × t – 35m + 35 m

180 m = 9 m/s × t

Divide both side by 9 m/s

t = 180 m / 9 m/s

t = 20 s

Therefore, the value of t is 20 seconds.

Answer:

The density of the substance precisely is 2142.8571428571, but you could always round the answer to something else.

Explanation:

The formula for finding density is ρ (density) equals mass over volume.

75 grams over 35 mL = 2.1428571428571 gram/mL = 2142.8571428571 kilogram/cubic meter.

Answer:

418.6 J

Explanation:

We know the specific heat for water is 4.186 kJ/kg * °C, so this can also write as 4.186 J/g * °C, so the heat increases 5 C in this question, so you can get 4.186(J/g * C) * 5C * 20g = 418.6 J

The statement which best describes the Oort cloud is that it contains huge icy objects and is therefore denoted as option B.

This is referred to as the mass of water drops or ice crystals suspended in the atmosphere and are of different types such as oort, cumulus etc. It is also involved in rain formation in the ecosystem.

Oort cloud on the other hand is defined as a hypothetical, spherical distribution of icy bodies located in the far reaches of the Solar system which is therefore the reason why option B was chosen as the correct choice.

Answer: Experimental design means creating a set of procedures to test a hypothesis. A good experimental design requires a strong understanding of the system you are studying. By first considering the variables and how they are related (Step 1), you can make predictions that are specific and testable (Step 2).

current = charge/time

All you have to take care of is the units should be in the same system

so

current = 12/(2*60)         ---------  2 min = 2*60 sec

current  = 12/120  = 0.1 amp

Answer:

v = 800 m/s

Explanation:

Given that,

Distance, d = 2400 m

Time, t = 3 s

We need to find the velocity of a rocket. Distance covered per unit time equals velocity. So,

[tex]v=\dfrac{d}{t}\\\\v=\dfrac{2400\ m}{3\ s}\\\\v=800\ m/s[/tex]

So, the velocity of the truck is 800 m/s.
