Answer:

200 newtons

Explanation:

because the sub air that would pull the force down by all of the mass of the sub air go down by that 400 newtons there for your anwer is 200 newtons. because 600-400=200

Answer:

200N

Explanation:

The net force or resultant force on the object is obtained by adding all the forces acting on it.

In this case we have an upward force and a downward force, since they go in different directions they must have a different sign: we will define upward as positive and downward as negative:

F_{air} = 400N

F_{grav}=-600N

The sign only to indicate that they are going in opposite directions, so the resulting force:

F=F_{air}+F_{grav}=400N+(-600N)=400N-600N=-200N

The net force acting on the object is 200N. (downwars due to the negative sign).

When Dr. Hewitt immerses an object in water the second time and catches the water that is displaced by the object, how does the
Dimas [21]

Answer:

Explanation:

- The volume of water displaced by immersing the object is equal the amount of water spilled and caught by Dr. Hewitt.

- The amount of water is proportional to the volume of object of fraction of object immersed in water will lead to the same fraction of water displaced and caught by Dr. Hewitt.  

- When the object is immersed the force of Buoyancy acts against the weight and reducing the scale weight.

- The amount of Buoyancy Force is proportional to the fraction of Volume of object immersed in water; hence, the same amount is spilled/lost.

At an outdoor market, a bunch of bananas attached to the bottom of a vertical spring of force constant 16.0 N/m is set into osci
aksik [14]

Answer:

Explanation:

Answer:

4.53 kg

Explanation:

spring constant, K = 16 N/m

Amplitude, A = 20 cm = 0.2 m

Maximum speed, v = 37.6 cm/s = 0.376 m/s

The formula for maximum speed is given by

v = ωA

where, ω is the angular frequency

0.376 = ω x 0.2

ω = 1.88 rad/s

\omega =\sqrt{\frac{K}{m}}

m = \frac{K}{\omega ^{2}}

m = \frac{16}{1.88 ^{2}}

m = 4.53 kg

Thus, the mass of banana bunch is 4.53 kg.

A force is a push or a pull. Under the right circumstances, anything can exert a force.
Sliva [168]

Answer:

Explanation:

the force that you applied caused the notebook to move.

the force applied on the notebook by the table causes it to stop moving.

this is because after sometime the book uses up the force and later the force you applied is less than that of the force by the table.

What is the direction of the magnetic field if an electron moving in the positive x direction experiences a magnetic force in th
Alex787 [66]

Given :

An electron moving in the positive x direction experiences a magnetic force in the positive z direction.

To Find :

The direction of the magnetic field.

Solution :

We know, force is given by :

\vec{F}=q(\vec{v}\times \vec{B)}

Here, q = -e.

\vec{F}=(-e)(\vec{v}\times \vec{B)}\\\\\hat{k}=(-e)(\hat{i}\times \vec{B})

Now, for above condition to satisfy :

\hat{i}\times \vec{B}=-\hat{k}

So, \vec{B}=-\hat{j}

Therefore, direction of magnetic field is negative y direction.

Hence, this is the required solution.
