Answer:

Explanation:

Buoyancy is a force that always acts in the upward direction against the weight of the immersed or semi-immersed object in the fluid. In any fluid( air or water) column pressure increases as we go deeper because of the overlying fluid. Here magnitude of the buoyancy force is proportional to the pressure difference.

What’s the force of a pitching machine on a baseball? Baseballs pitched by a machine have a horizontal velocity of 30 meters/sec

Leya [2.2K]

The acceleration of the baseball is:
$a= \frac{v_f-v_i}{\Delta t}$
where $v_f$ and $v_i$ are the final and initial speed of the ball, and $\Delta t$ is the time interval in which the force acted.

Replacing the numbers, we get
$a= \frac{30 m/s-0m/s}{0.5 s}=60 m/s^2$
And at this point, we can use Newton's second law F=ma to find the value of the force of the pitching machine:
$F=ma=(0.15 kg)(60 m/s^2)=9 N$

Electromagnets are created by

Scrat [10]

I electromagnets, the magnetic field is turned off when there is no induced current. So, electromagnets act as magnets only when current is induced in an insulated wire wrapped around a material mage of ferromagnetic material such as iron core rotating in a magnetic field.

So, option D is the correct one.

If you wanna know more about electromagnets, write down in comments {:

2. Another car weighs 2000kg, you can push it .05 m/s?, how much force are you

Vesna [10]

Answer:

$\boxed {\boxed {\sf 100 \ Newtons}}$

Explanation:

We are asked to calculate the force you are applying to a car. According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, we can use the following formula to calculate force.

$F= m \times a$

The mass of the car is 2000 kilograms and the acceleration is 0.5 meters per second squared.

m= 2000 kg
a= 0.05 m/s²

Substitute the values into the formula.

$F= 2000 \ kg \times 0.05 \ m/s^2$

Multiply.

$F= 100 \ kg *m/s^2$

Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 100 kilogram meters per second square is equal to 100 Newtons.

$F= 100 \ N$
