Answer:

12 m/s²

Explanation:

We have Newton's 2nd Law of Motion:

F = ma (Force is equal to [constant] mass times acceleration)

Mass m is in kg and acceleration a is in m/s²

Our 1st acceleration given to us is a = 6 m/s². Let's substitute it into Newton's 2nd Law of Motion:

F = m(6 m/s²)

We are told that the net force doubles, meaning that the new force is 2F:

2F = ma

Mass doesn't change in this system; it is held constant due to Newton's 2nd Law of Motion. Therefore, to increase the net force acted on the object, the acceleration must change.

Since we are doubling the net force and mass stays constant, then acceleration also must double.

Therefore, our answer is (6 m/s²) · 2 = 12 m/s².

Marcie shovels snow after a storm by exerting a force of 32 N on her shovel at an angle of 50 degrees to the vertical. What is t

gulaghasi [49]

Answer:

The horizontal component of the force exerted by Marcie is 25 N

Explanation:

Lets explain how to solve the question

Marcie shovels snow after a storm by exerting a force of 32 N on her

shovel at an angle of 50 degrees to the vertical

We need to find the horizontal component of the force exerted by Marci

The force direction is 50° to the vertical means

→ tan(50) = $\frac{Fx}{Fy}$ , where x is the horizontal component

of the force and y is vertical component

→ tan(50) = $\frac{sin(50)}{cos(50)}$

By comparing between the two expressions of tan(50)

→ The horizontal component is Fx = F sin(50)

→ The vertical component is Fy = F cos(50)

We need the horizontal component

→ F = 32 N

→ The horizontal component = 32 sin(50) = 24.51 N ≅ 25 N

The horizontal component of the force exerted by Marcie is 25 N

List the requirements of practical fuel?

rewona [7]

Answer:

Here we have some of the requirement of practical fuel are

1. It must contain large amount of stored energy. So that more amount of power output available to run the engines, motors etc.

2. It must occur in abundance in nature or be easy to produce.

3. The fuel must be made up of elements that combine easily with oxygen. Foe example if hydrogen molecules reacts with oxygen. Then the products are at the reaction of lower energy than the reactants, the result is the explosive release of energy and the product of water.

For a ship moving against the current, it takes 9 hours to cover a distance of 113.4 miles. how much does it take this ship to r

Digiron [165]

Let x mph be the speed of the ship in still water.
Against the current, the net speed is, (x-1.9) mph.
Time, t= distance, d/ Speed, v => 9= 113.4/(x-1.9) => 9(x-1.9) = 113.4 => x-1.9 = 113.4/9 => x = 12.6+1.9 = 14.5 mph

Moving with the current, the net speed of the ship = 14.5+1.9 =16.4 mph

Time take, t = d/v = 113.4/16.4 = 6.915 hours

A dog can hear sounds in the range from 15 to 50,000 hz. what wavelength corresponds to the lower cut-off point of the sounds at

Ira Lisetskai [31]

The frequency corresponding to the lower cut-off point is
$f=15 Hz$
The speed of sound at a temperature of $20^{\circ}C$ is approximately
$v=343 m/s$

Therefore we can use the relationship between speed of a wave, frequency and wavelength to calculate the corresponding wavelength:
$\lambda= \frac{v}{f}= \frac{343 m/s}{15 Hz}=22.87 m$
So, the corresponding wavelength is 22.87 m.
