Answer the question?
He likes to eat (into passive voice)
Answer:
yes he does
Explanation:
Solar energy heats the surface of the Earth, including the ground, rocks, and even roadways. As the temperature of these surfaces increases, heat energy is released back into the atmosphere, forming a pocket of warm air. As the warm air pocket rises, it is replaced by cooler air. This process is responsible for many of the weather patterns in our atmosphere and is known as

So your answer would be A.
Answer: C
Explanation:
all the other ones are part of the cell theory
A boat trip travels are 15 miles in the direction of 45° east of north for an hour the boat then turn and travels at 18 m/s in a direction 5° north of East for an hour
Answer:
Hello your question is incomplete below is the missing piece
What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.
answer : 25.73 m/s
Explanation:
Given
V1 = 15 miles/hour = 6.71 m/s [ 45° EN ]
V2 = 18 m/s [ 5° NE ]
Calculate the resultant velocity
Vr = 6.71 m/s[45°] + 18m/s[5°].
Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )
Vr = ( 4.74 + 4.74 i )+ ( 17.93 + 1.57i) = 22.67 + 12.18i.
Therefore the magnitude
= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s

Explanation:
Three charges lie along the x-axis. One positive charge, q1 = 4.80*10^-18 C, is at x = 3.72 m, and another positive charge, q2 = 1.60*10^-19 C, is at the origin.
At what point on the x-axis must a negative charge, q3, be placed so that the resultant force on it is zero?
Answer:
The third charge needs to be placed at [tex]x \approx 0.57\; \rm m[/tex].
Explanation:
Both [tex]q_1[/tex] and [tex]q_2[/tex] would attract [tex]q_3[/tex].
These two electrostatic attractions need to balance one another. Hence, they need to be opposite to one another. Therefore, [tex]q_1[/tex] and [tex]q_2[/tex] need to be on opposite sides of [tex]q_3[/tex]. That is possible only if [tex]q_3 \![/tex] is on the line segment between [tex]q_1 \![/tex] and [tex]q_2 \![/tex].
Assume that [tex]q_3[/tex] is at [tex]x\; \rm m[/tex], where [tex]0 < x < 3.72[/tex] (in other words, [tex]q_3 \![/tex] is on the line segment between [tex]q_1[/tex] and [tex]q_2[/tex], and is [tex]x\; \rm m \![/tex] away from [tex]q_2 \![/tex].)
Let [tex]k[/tex] denote Coulomb's constant.
The magnitude of the electrostatic attraction between [tex]q_1[/tex] and [tex]q_3[/tex] would be:
[tex]\displaystyle \frac{k\cdot q_1 \cdot q_3}{(3.72 - x)^{2}}[/tex].
Similarly, the magnitude of the electrostatic attraction between [tex]q_2[/tex] and [tex]q_3[/tex] would be:
[tex]\displaystyle \frac{k\cdot q_2 \cdot q_3}{x^{2}}[/tex].
The magnitudes of these two electrostatic attractions need to be equal to one another for the resultant electrostatic force on [tex]q_3[/tex] to be [tex]0[/tex]. Equate these two expressions and solve for [tex]x[/tex]:
[tex]\displaystyle \frac{k\cdot q_1 \cdot q_3}{(3.72 - x)^{2}} = \frac{k\cdot q_2 \cdot q_3}{x^{2}}[/tex].
[tex]\displaystyle \frac{q_1}{(3.72 - x)^{2}} = \frac{q_2}{x^{2}}[/tex].
[tex]\displaystyle \frac{x^2}{(3.72 - x)^{2}} = \frac{q_2}{q_1}[/tex].
[tex]\displaystyle \frac{x^2}{(3.72 - x)^{2}} = \frac{q_2}{q_1} = \frac{1}{30}[/tex].
By the assumption that [tex](0 < x < 3.72)[/tex], it should be true that [tex](x > 0)[/tex] and [tex](3.72 - x > 0)[/tex]. Therefore, [tex]\displaystyle \frac{x}{(3.72 - x)} > 0[/tex].
Take the square root of both sides of the equation [tex]\displaystyle \frac{x^2}{(3.72 - x)^{2}} = \frac{1}{30}[/tex].
[tex]\displaystyle \sqrt{\frac{x^2}{(3.72 - x)^{2}}} = \sqrt{\frac{1}{30}}[/tex].
[tex]\displaystyle \frac{x}{3.72 - x} = \frac{1}{\sqrt{30}}[/tex].
[tex]\sqrt{30}\, x = 3.72 - x[/tex].
Therefore:
[tex]\left(1 + \sqrt{30}\right)\, x = 3.72[/tex].
[tex]\displaystyle x = \frac{3.72}{1 + \sqrt{30}} \approx 0.57[/tex].
Hence, [tex]q_3[/tex] should be placed at [tex]x \approx 0.57\; \rm m[/tex].
A car travels 52 mph for 6 minutes, 46 mph for 3 minutes, 40 mph for the remaining time during a 30 minute journey. find the total distance travelled
Answer:
21.5 miles
Explanation:
Distance = Speed * time
Distance traveled in first 6 minutes = 52 * [tex]\frac{6}{60}[/tex] = 5.2 miles
Distance traveled in next 3 minutes = 46 *[tex]\frac{3}{60}[/tex] = 2.3 miles
Remaining minutes = 30 - 6 -3 = 21 minutes
Distance traveled in 21 minutes = 40 * [tex]\frac{21}{60}[/tex] = 14 miles
Total distance traveled = 5.2 + 2.3 + 14 = 21.5 miles

Machines get heated up and produce noise because of friction.
Explain how a current is induced in the wire?
Answer:
If a coil of wire is placed in a changing magnetic field, a current will be induced in the wire. This current flows because something is producing an electric field that forces the charges around the wire. (It cannot be the magnetic force since the charges are not initially moving). ... that determines the induced current.

round answer to two significant figures
note that time is in ms.
Answer: 0.15 m/s
Explanation:
how does displacement, acceleration, time, and velocity affect motion?
Answer:
The relation between velocity and time is a simple one during uniformly accelerated, straight-line motion. The longer the acceleration, the greater the change in velocity. Change in velocity is directly proportional to time when acceleration is constant.
~Hoped this helped~
~Brainiliest?~
Answer:
We describe motion in terms of velocity and acceleration. Velocity: The rate of change of displacement of an object (displacement over elapsed time) is velocity. Velocity is a vector since it has both magnitude (called speed) and direction. ... Acceleration: The rate of change of velocity is acceleration.
Explanation:
Displacement is a vector which points from the initial position of an object to its final position. ... Instantaneous velocity, on the other hand, describes the motion of a body at one particular moment in time. Acceleration is a vector which shows the direction and magnitude of changes in velocity.
Displacement is the vector difference between the ending and starting positions of an object. Velocity is the rate at which displacement changes with time. ... The average velocity over some interval is the total displacement during that interval, divided by the time.

Hi people; there's a question that has been so confusing for me and a friend of mine.
0°C + 0°C = 64°F
Is this correct or wrong?
Answer:
The correct answer is: 0°C + 0°C = 32°F
Explanation:
We need to remember the conversion equation from Celsius to Fahrenheit:
[tex]y^{\circ}F=(x^{\circ}C * \frac{9}{5})+32[/tex]
In our case x = 0, then y will be:
[tex](0^{\circ}C * \frac{9}{5})+32=32[/tex]
[tex]y=32^{\circ}F[/tex]
Now 0°C + 0°C is just 0°C because if we add a body at a certain temperature to another body with the same temperature the total temperature will the same.
Then, knowing that 0°C = 32°F we can conclude that:
[tex]0^{\circ}C+0^{\circ}C=32^{\circ}F[/tex]

You wake up in the morning and get out of bed. Does the floor feel cold or warm on your bare feet? On the lines below, write a sentence that compares how it feels to step on a bare floor and on a rug on a cold morning
When you get out of bed in a morning it's most likely too be cold so your bare feet on a floor not carpet a bare floor will feel cold since the temperature and molecules had changed and if you step on a warm fuzzy rug it will feel warm since your feet are cold and the rugs fuzziness or material keeps you warn
We feel more cold on feet on morning because heat from our feet will flow to the cold floor. We feel more cold on the bare floor than the rug since it conducts heat away from our feet.
What is heat transfer?Heat will be transfer on a temperature gradient from one substance to the other. Heat is transferring from the hot body to the colder body. There are three types of heat transfer are there namely, conduction, convection and radiation.
Conduction is the heat transfer in solids , convection in liquids and radiation is the heat or energy transfer mode in gases and vacuum. At the morning, the floor will be more cool whereas our body will be hotter, thus heat will flow our body to floor make our feet cool.
A bare floor will conduct thermally more than a rug do. Thus the bare floor conducts heat away from our feet and make our feet more cool.
