A force F produces an acceleration a on an object of mass m. A force 3F is exerted on a second object, and an acceleration 8a re

Pie

To solve this problem we will proceed to use Newton's second law for which the mass (m) multiplied by the acceleration (a) is defined as the Force (F) applied on a body, mathematically that is,

$F = ma$

According to the statement for the first object, the acceleration is,

$a = \frac{F}{m} \rightarrow 1^{st} Object$

For the second object the acceleration is,

$8a = \frac{3F}{m_2} \rightarrow 2^{nd} Object$

Solving for the mass of the second object,

$m_2 = \frac{3F}{8a}$

$m_2 = \frac{3F}{8(F/m)}$

$m_2 = \frac{3}{8}m$

Therefore the correct answer is D.

What happens to speed when wavelength decreases

Phantasy [73]

Speed = wavelength × frequency

giving that frequency is 0, wavelength and speed are directionally proportional. wavelength decrease = speed decrease

Well, basically both Cheryl and Keaton is right.

matter is described as Physical substance that possessed space and mass.

But the thing is, one matter is very small in size and cannot be seen with naked eyes. But everything around us are made by matters

4. A disobedient student dropped his Physics textbook (mass 0.1kg) from the window (15m above the ground). How fast was it going

vaieri [72.5K]

Answer:

v= 17.15 m/s

Explanation:

mass of the book=0.1 Kg

height above ground, h= 15 m

Using conservation of energy

Potential energy is converted into kinetic energy

$mgh = \frac{1}{2}mv^2$

$v=\sqrt{2gh}$

$v=\sqrt{2\times 9.8\times 15}$

$v=\sqrt{294}$

v= 17.15 m/s

Hence, the book will hit the ground at the speed of 17.15 m/s.

Use the graph below to answer the following question: What is happening to the object's velocity?

hjlf

The object's velocity is decreasing.

Explanation:

From graph is the attached image, we can clearly point that the velocity of this motion is decreasing with time.

Velocity is a vector quantity.

The y-axis represent displacement.
The x-axis depicts time
Using the graph, we know that the slope of the line on the graph gives us the velocity as it denotes the change of displacement with time.
When we find the slope, it will give us a negative value which shows that the body is slowing down and not increasing speed.
