Answer:

see below

Explanation:

First, the obvious, as you press the gas pedal harder the acceleration goes up as well. Conversely, is you do not press the pedal, you will not accelerate. This determines that is I press the gas pedal, it will CAUSE the car to accelerate. This proves causation.

Now, correlation. The definition of correlation in statistics is any statistical relationship between two random variables or data. This simply means that these two events are connected to one another. A POSITIVE correlation is when two correlated events move in the same direction as one another. I have added a graph to help visualize this. In this problem as the gas is pressed harder, the acceleration increases. If the pressure on the pedal was decreased, then the acceleration also decreases. If the pressure on the pedal is constant, the the acceleration is constant.

I hope this helps!

You are taking care of two small children, Sarah and Rachel, who are twins. On a nice cool, clear day you decide to take them ro

BlackZzzverrR [31]

Answer:

Explanation:

Rachel and Sarah are standing on horizontal ground . Let T₁ be the tension between Rachel and Sarah and Sarah is in between you.

Force = mass x acceleration

Apply this equation on Rachel

T₁ = 23 x 2 = 46 N

Let T₂ be tension between Sarah and me and it is inclined at 60°

Force = mass x acceleration

Apply this equation on Sarah

T₂ cos 60 - T₁ = 23 X 2 = 46

T₂ cos 60 - 46 =46

T₂ cos 60 = 92

T₂ = 92 / .5

= 184 N

When none of the magnetic domains in a material will stay aligned, the material is called __________________?

Kisachek [45]

The material is called paramagnetic or non magnetic material. Opposite to this are materials whose magnetic domains are aligned and possess asmagnetism which is due to its ferrous or iron content.

Now solve the differential equation V(t)=−CRdV(t)dt for the initial conditions given in the problem introduction to find the vol

mina [271]

Answer:

V(t) = (q0/C) * e^(−t/RC )

Explanation:

If there were a battery in the circuit with EMF E , the equation for V(t) would be V(t)=E−(RC)(dV(t)/dt) . This differential equation is no longer homogeneous in V(t) (homogeneous means that if you multiply any solution by a constant it is still a solution). However, it can be solved simply by the substitution Vb(t)=V(t)−E . The effect of this substitution is to eliminate the E term and yield an equation for Vb(t) that is identical to the equation you solved for V(t) . If a battery is added, the initial condition is usually that the capacitor has zero charge at time t=0 . The solution under these conditions will look like V(t)=E(1−e−t/(RC)) . This solution implies that the voltage across the capacitor is zero at time t=0 (since the capacitor was uncharged then) and rises asymptotically to E (with the result that current essentially stops flowing through the circuit).

A 30-kg object on Venus weighs 266.1 N. What is the value of gravity on Venus? A. 8.87 m/s2

Marat540 [252]

The weight force on an object in a gravitational field is given by $F = mg$ where $m$ is the mass in kg and $g$ is the acceleration<span> due to gravity at that place. Rearranging:
</span> $g = \frac{F}{m} = \frac{266.1}{30} = 8.87 Nkg^&-1$ or $8.87ms^&-2$
Explanation:

Venus is only slightly smaller than Earth, in both mass and radius, so this answer makes sense, when compared with the value of $9.81 Nkg^&-1$ <span>at Earth's surface.</span>
