Answer:
B) The Gulf Stream carries warm water along the east coast, causing average temperatures to be warmer than they would be without the current.
Explanation:
The east coast of the United States is affected mainly by the Gulf Stream current, which brings warm water from the tropics into higher latitudes. Because warmer water evaporates faster, putting more moisture into the air, the current serves to increase the humidity of the air along the coast.

what happens to the motion of objects when they hit each other?
Answer:
When two objects in motion hit each other they experience forces that are equal in magnitude and opposite in direction. This force causes one of the objects to speed up or gain momentum and other to slow down or lose momentum.
Cual es la rapidez media de un guepardo que recorre 100 metros en 4 segundos? ¿Y si recorre 50 m en 2 s?
Answer:
La rapidez media es 25 m/s en ambos casos.
Explanation:
Podemos definir como rapidez media al cociente entre la distancia total recorrida y el tiempo que se tardó en recorrer dicha distancia.
Así tenemos:
Rapidez media = Distancia/tiempo.
Entonces si el guepardo recorre 100m en 4 segundos, su rapidez media es:
Rapidez media = 100m/4s = 25 m/s
En el caso de que el guepardo recorre 50 metros en 2 segundos, su rapidez media será:
rapidez media = 50m/2s = 25m/s
Es el mismo resultado, pues recorrió la mitad de distancia en la mitad de tiempo.
Plants cause weathering, too. A seed that falls into a crack in a rock may grow there. Growing roots may push on and enlarge the crack, What is this process called Question 2 options: chemical weathering mechanical weathering root-pry pedalfer
Answer:
c. root-pry
Explanation:

The process by which a seed enters a rock fracture and the expanding roots push to widen the fissures is known as mechanical weathering.
What do you mean by mechanical weathering?Machine-induced weathering Mechanical weathering, sometimes referred to as physical weathering and disaggregation, causes rocks to break down. Water, whether liquid or solid, is usually present during mechanical weathering. For instance, liquid water may seep through fractures and fissures in rock.
You may get mechanical weathering from
the reduction in pressure produced on by the removal of subsurface rock.
Water freezes and thaws in the granite's crevices.
Salt crystals are developing inside the rock.
cracking brought on the plant roots and exposed by digging animals
The information is ,
Let's say the weathering looks like A.
Now, plants are to blame since a seed that falls into a fracture in a rock and the seed's expanding roots push and widen the original gap
Weathering from mechanical sources and one mechanical weathering mechanism that fractures rocks is the freezing and spreading of ice in rock cracks.
Moreover, mechanical weathering reduces rocks into microscopic fragments, increasing the surface area of the material as a whole.
Hence, the method is mechanical weathering.

The fire alarm goes off, and a 75 kg firefighter slides down a pole with a constant acceleration of a = 6 m/s square. What is the upward force F exerted by the pole on the firefighter? *
Answer:
450N
Explanation:
Given data
Mass m= 75kg
Acceleration= 6m/s^2
From the Newtons first law, F=ma
substitute
F=75*6
F= 450N
Hence the force is 450N

Why is this statement false?
As the temperature of water is decreased from 4C to 0C contraction occurs.
The statement is false because as the temperature of water is decreased from 4C to 0C, expansion occurs.
You should understand that this is very weird behavior for any compound ... within a small temperature range, the stuff actually gets bigger as it gets colder. That's why cubes float in your sody, and bergs float in the ocean.
Water is one of only two known substances that do this. And if water didn't do it, then life on Earth would not be possible.
Hmmm....
There is not contraction, Instead expansion occurs .
We know density of water is temperature dependant .
at 4°C water has max density so least volume as density is indirectly proportional to volume.
at 0°C density decreases so volume increases

An arrow is shot at an angle of 35° and a velocity of 50 m/s. How long does it take to return to its original starting height?
Answer:
4.02 s
Explanation:
From the question given above, the following data were obtained:
Angle of projection (θ) = 35°
Initial velocity (u) = 50 m/s
Acceleration due to gravity (g) = 10 m/s²
Time of flight (T) =?
The time of flight of the arrow can be obtained as follow:
T = 2uSineθ / g
T = 2 × 35 × Sine 35 / 10
T = 70 × 0.5736 / 10
T = 7 × 0.5736
T = 4.02 s
Therefore, the time taken for the arrow to return is 4.02 s

A circus stuntman holds himself straight out by his arms from a vertical pole. If the stuntman's center of gravity is located 0.75 m away from the pole and he weights 650 N, how much force do is arms have to apply if they exert their force upwards at 0.10 m away from the pole? [4875 N]
Answer: 4875 N
Explanation:
Given
Stuntman weight is [tex]W=650\ N[/tex]
His center of gravity is located at [tex]x=0.75\ m[/tex] away from pole
If he applies an upwards force at 0.10 m away from the pole
Suppose F is the applied force
To remain vertical, the torque of weight must be canceled by the vertical force
[tex]\Rightarrow 650\times 0.75-F\times 0.10=0\\\\\Rightarrow 650\times 0.75=F\times 0.10\\\\\Rightarrow F=\dfrac{487.5}{0.10}=4875\ N[/tex]
It is the disturbance or oscillation that travels through space and matter, accompanied by a transfer of energy.
Answer:
wave
Explanation:
A wave is defined as the disturbance that causes the movement of energy. The energy is transferred as the waves move from one place to another. A medium is required for the transfer of energy. Usually a wave travels through air or water. The process is carried on at a specific speed that is termed as the speed of propagation.
A new piece of exercise equipment has been added to your gym, and you try it out. To use this machine, you lie horizontal on a mat with your feet against a platform perpendicular to the mat. The platform is held by a stiff spring that is compressed when the platform moves. Your workout invovles compressing the spring by pushing on the platform with your feet. After testing compressions of the equipment, you determine that you must do 85.0 J of work to compress the spring a distance 0.170 m from its uncompressed length.What magnitude of force must you apply to hold the platform stationary at the final distance given above
Answer:
500 N
Explanation:
Since the work done on the spring W = Fx where F = force applied and x = compression length = 0.170 m (since the spring will be compressed its full length when the force is applied)
Since W = 85.0 J and we need to find F,
F = W/x
= 85.0 J/0.170 m
= 500 N
So, the magnitude of force must you apply to hold the platform stationary at the final distance given above is 500 N.
