The answer is 4 grams because matter can neither be created or destroyed and according to the laws of physics, you need 4 grams for 4 grams.

Answer:

the magnetic field is leaving the sheet

Explanation:

The magnetic force is given by the expression

        F = q v x B

where bold letters indicate vectors, the modulus of this expression is

       F = q v B sin θ

the direction of the force is given by the right hand rule, for a positive charge

the thumb indicates the direction of the speed, in this case from right to left

the palm the direction of the force, in our case upwards

the fingers extended the direction of the magnetic field, this case after fixing the other two components it points out of the blade

In short the magnetic field is leaving the sheet

In what condition do acceleration and deaccelration<br>​
Vera_Pavlovna [14]

Im not sure what are you asking about. But in physic/ mechanic usually when the object against gravity, its deceleration but when the object follow the gravity its acceleration

Also usually when the object move to the left side the speed will be negative (-) this is probably because of deceleration? since deceleration = -acceleration.

The gage pressure in a liquid at a depth of 3 m is read to be 50 kPa. Determine the gage pressure in the same liquid at a depth
Andrei [34K]

Answer:

The Gauge pressure at 9 meters depth is 150 \, kPa

Explanation:

Gauge pressure is the difference between absolute pressure and some reference pressure, most commonly atmospheric pressure. The increment in pressure caused by a static fluid is given by:

\Delta P = \rho g d where \rho is the density of the liquid,  g is the accleration due to gravity and d is the depth.

Now, we see that \Delta P is linearly proportional to d, and we can assume that \rho remains constant, because liquids are usually not compressible.

Given that the greater depth is simply 3 times the smaller depth:

d_2=3\cdot d_1\\9\,m= 3 \cdot 3\,m

\Delta P at 9\, m of depth will also be three times the gauge pressure at 3 \,m of depth.

We could also have calculated \rho ny using:

\Delta P = \rho \,g \,d\\\\\rho = \frac{\Delta P}{g \, d}\\\\\rho = \frac{\Delta P}{g \, d}= \frac{30 \,kPa}{9.8 \frac{m}{s^2}  \, 3\,m}=1020.41 \frac{kg}{m^3}

and used this result to calculate the gauge pressure. These are both similar methods that yield the same result

What is the Range of the projectile motion?
never [62]

Answer:

Range of projectile, R

For projection above ground surface, the range of the angle of projection with respect to horizontal direction, θ, is 0° ≤ θ ≤ 90° and the corresponding range of 2θ is 0° ≤ 2θ ≤ 180°.S

hope you're looking for this.
