Answer:
what is the question. . .
Answer:
see the answer above
Explanation:
If the Sun, Earth, and Moon are lined up as shown, the Earth would have______.
A. Spring tides where there is almost no difference in the tides
B. Spring tides, which is where there are very high tides and very low tides
C. Neap tides where there is almost no difference in the tides.
D. Neap tides, which is where there are very high tides and very low tides
Answer:
The answer is B. Spring tides, which are where there are very high tides and very low tides.
Explanation:
Spring tides occur when the sun and the moon are in alignment with Earth.
At the time of a new moon or full moon when the sun, earth, and the moon are in full alignment the solar tide affects the lunar tide leading to the creation of extra-high high tides, and very low, low tides. The basic reasons for this phenomenon are the gravity of the sun and the moon is acting on the earth oceanPlease thank my answer and vote. (Maybe mark brainliest please)

The Brazilian rain forest is an area with significant biodiversity.
As the rain forest is replaced with agricultural land, it is
reasonable to predict a reduction in -
consumption of solar energy.
sustainability over time.
precipitation levels.
average daily temperature.
Answer:
sustainability over time.
Explanation:
The largest Brazilian rainforest is the Amazon rainforest, which is the largest rainforest in the world and occupies 42% of the Brazilian territory. The forest is composed of a rich environmental diversity, constituted by many species of fauna and flora and diverse river resources.
However, there is a growing transformation in the Amazon rainforest caused by organizational exploitation that uses its resources to transform the forest area into agricultural land and pastures for livestock. This problem will cause a reduction in sustainability over time, which will cause serious negative effects on the environment, such as a reduction in biodiversity and an increase in the emission of gases responsible for the greenhouse effect on the planet.

A container of carbon dioxide has a volume of 315 cm³ at a temperature of 25°C if the pressure remains constant what is the volume of 54°C
Answer:
680.4
Explanation:
the formula is V1 over T1 is equals (=) to V2 over T2 .
and we have been given that
V1 represents 315
T1 represents 25°c
V2 is unknown and what we're finding
T2 represents 54°c
so 315×54 all over 25 ...gives you 680.4

An airplane traveling 919 m above the ocean at 505 m/s is to drop a case of twinkies to the victims below. How much time before being directly overhead should the box be dropped? What is the horizontal distance between the plane and the victims when the box is dropped?
Answer:
a. 13.7 s b. 6913.5 m
Explanation:
a. How much time before being directly overhead should the box be dropped?
Since the box falls under gravity we use the equation
y = ut - 1/2gt² where y = height of plane above ocean = 919 m, u = initial vertical velocity of airplane = 0 m/s, g = acceleration due to gravity = -9.8 m/s² and t = time it takes the airplane to be directly overhead.
So,
y = ut - 1/2gt²
y = 0 × t - 1/2gt²
y = 0 - 1/2gt²
y = - 1/2gt²
t² = -2y/g
t = √(-2y/g)
So, t = √(-2 × 919 m/-9.8 m/s²)
t = √(-1838 m/-9.8 m/s²)
t = √(187.551 m²/s²)
t = 13.69 s
t ≅ 13.7 s
So, the box should be dropped 13.69 s before being directly overhead.
b. What is the horizontal distance between the plane and the victims when the box is dropped?
The horizontal distance x between plane and victims, x = speed of plane × time it takes for box to drop = 505 m/s × 13.69 s = 6913.45 m ≅ 6913.5 m

) A spring with a spring constant of 2.1N/m is stretched 0.2m. What force is produced by
the spring?
Answer:
Force = 0.42 Newton
Explanation:
Given the following data;
Spring constant, k = 2.1
Extension, e = 0.2m
To find the force, we would use the formula below;
Force = spring constant * extension
Force = 2.1 * 0.2
Force = 0.42 Newton

A skateboarder traveling at 7.0 meters per second rolls to a stop at the top of a ramp in 3.0 seconds. What is the skateboarder’s acceleration?
*Please only answer if you know - and ABSOLUTLEY NOOOOOOOO LINKS*
Thank you! :)
Answer:
-2.33 m/s²
Explanation:
The computation of the skateboarder’s acceleration is shown below;
Acceleration means the change in velocity per unit with respect to time.
In the given case, the initial velocity is 7 m/s.
As in the question it is mentioned that it comes to a stop, so the final velocity would be zero.
And, The time elapsed is 3 seconds.
Now the following equation should be used
a = (v,final - v,initial) ÷ t
= (0 - 7)/3
= -2.33 m/s²

Light travels through a material at a speed of 4.3 x 108 m/s. What is the index of
refraction for the material?
Your Answer:
Answer
units
Answer:
η = 0.7
Explanation:
The refractive index of the material can be calculated by using the following formula:
[tex]\eta = \frac{c}{v}\\[/tex]
where,
η = refractive index of the material = ?
c = speedof light in vaccuum = 3 x 10⁸ m/s
v = speed of light in this material = 4.3 x 10⁸ m/s
Therefore,
[tex]\eta = \frac{3\ x\ 10^8\ m/s}{4.3\ x\ 10^8\ m/s}[/tex]
η = 0.7

An elevator lifts a total mass of 1800 kg, a distance of 60 m in 60 s. How much power does the elevator generate?
Answer:
17640
Explanation:
Power = workdone/time
Power = (force x displacement)/time
Power = (mg x 60)/60
Power = (1800 x 9.8 x 60)/60
=> power = 17640 watt
Which is a characteristic of the image formed by an
object between 2F and F?
O The image is virtual.
O The image is bigger than the object.
O The image is inverted,
O
When the object is placed between 2F and F in front of a concave lens characteristic of the image formed by an object is virtual, therefore the correct option first option that the image is virtual.
What is refraction?
It is the phenomenon of bending of light when it travels from one medium to another medium. The bending towards or away from the normal depends upon the medium of travel as well as the refractive index of the material.
Snell's law,
n₁sin(θ₁) = n₂sin(θ₂)
Where n is the refractive index and θ represents angles
A concave lens is used to diverge the incident rays of light falling on it. because of this, the image formed by the concave lens is virtual.
These concave lenses are used in several days to day life applications such as cameras, telescopes, and eye glasses.
When the object is placed between 2F and F in front of a concave lens the characteristic of the image formed by an object is virtual. therefore the correct option first option is that the image is virtual.

Which car traveled at a constant speed throughout its motion?
O AW
ОВ. Х
О O c.ru
OD. Z
Answer:
Answer is A
Explanation:
As we know , for constant velocity we get a straight line.
The formula for this problem is s = vt which is similar to a straight line formula like y = mx + c.
If we put here c = 0 we get the formula for distance and velocity.
So the answer is A.
The greater the mass of an object being moved, the greater amount of force needed to move the object,

It's often called the law of inertia. Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). ... A more massive object has a greater tendency to resist changes in its state of motion.
