Which trailer has more downward pressure where it attaches to the car?

1 answer:

4 0

The trailer that is loaded the most. The total weight does not matter; it is about how the load is distributed. For example, our 12,000 lb snow cat trailer has weight distribution that results in less than 100 lbs of tongue weight. Heavy tongue weight can create issues, as it can shift the weight off the front wheels of the towing vehicle, causing instability.

Sav [3153]

The total duration from the stone's drop to the echo being heard is 8.9 seconds. The sound takes 0.9 seconds to reach the listener, meaning it takes the stone 8 seconds to descend to the well's bottom. Using gravitational acceleration, the well's depth calculates to be approximately 313.6 meters.

Multiply the number 4.48E-8 by 5.2E-4 using Google. What is the correct answer in scientific notation?

Ostrovityanka [3204]

Answer:

$2.32\times 10^{-11}$

Explanation:

The first number is $4.48\times 10^{-8}$ .

The second number is $5.2\times 10^{-4}$ .

We must multiply these two numbers together.

$4.48\times 10^{-8}\times 5.2\times 10^{-4}=(4.48\times 5.2)\times 10^{(-8-4)}\\\\=23.296\times 10^{-12}$

In scientific notation: $2.32\times 10^{-11}$

Therefore, this is the solution you are looking for.

A 1000-kg car is moving along a straight road down a 30∘30∘ slope at a constant speed of 20.0m/s20.0m/s. What is the net force a

Softa [3030]

The overall force acting on the vehicle is zero

Explanation:

Let's evaluate the situation separately for the vertical direction and the horizontal direction along the slope.

Considering the direction perpendicular to the slope, two forces are in effect:

The weight component acting perpendicular to the slope, $mgcos \theta$ , directed into the slope
The normal force N, directed outward from the slope

Equilibrium exists here, indicating the net force in this direction is zero.

Now let’s examine the parallel direction to the slope. We have two forces present:

The weight component aligned with the slope, $mgsin \theta$ , directed down the slope
The frictional force $F_f$ , acting up the slope

The car moves at a constant speed in this direction, indicating that its acceleration is zero.

$a=0$

Thus, according to Newton's second law,

$F=ma$

implying the net force is zero:

$F=0$

ValentinkaMS [3465]

In this scenario, there exists a constant electric field produced by a large sheet. This electric field can be defined as... The force acting on the ball due to this field acts horizontally, and this force must be counterbalanced by the horizontal tension component of the string to maintain equilibrium. Similarly, the vertical tension component in the string must equal the weight of the small sphere. Hence, we can derive two equations to illustrate this.
