I think what’s wrong is that the paper clip isn’t connecting to the other thing on the bottom

Two objects, one having three times the mass of the other, are dropped from the same height in a vacuum. At the end of their fal

gogolik [260]

Answer:

Two objects will have the equal velocities but the forces on both of them will not be equal. The equal velocities of these objects are due to their equal acceleration.

Explanation:

From the newton's equation

$v^{2} -u^{2} = 2as$

so here we can say that velocity does not depends on the mass.

The acceleration of both objects will be same but not the forces because

F = Ma

As the force is depending on the mass so it will not be the same for both objects.

Answer: Virtual, upright and diminished.

Explanation:

A transparent material that focuses or diverges light is known as a lens. There are mainly two types of lens: concave lens and convex lens. Other lens can be made using combination of these two and plane one.

A concave lens is a diverging lens. It means the light from any real object after passing through this lens appears to diverge from the focus. A image formed by a diverging lens is virtual, upright and diminished.

Part A : A cylindrical water tank 10cm high and 520cm in diameter is filled with solution with a density of 0.75 g/cm^3

lisov135 [29]

Answer: $0.1066\ psi, 15.611\ kN$

Explanation:

Given

the height of the tank is $h=10\ cm$

The diameter of the tank is $d=520\ cm$

Density of solution $\rho=0.75\ g/cm^3\ or\ 750\ kg/m^3$

$(a)$ Water pressure at the bottom of the tank is

$P=\rho gh\\P=750\times 9.8\times 0.1\\P=735\ Pa$

$1\ Pa=0.000145038\ psi$

$\Rightarrow P=735\ Pa\ or\ 0.1066\ psi$

$(b) \text{Average force on the bottom is the product of pressure and area of the base}$

$F_{avg}=735\times \pi \cdot (\frac{520}{200})^2\\\\F_{avg}=735\times 3.142\times 6.76\\F_{avg}=15,611.34\ N\ or\ 15.611\ kN$

ou have just moved into a new apartment and are trying to arrange your bedroom. You would like to move your dresser of weight 3,

Dimas [21]

So far, since you moved into the apartment until the end of this much of the story, you haven't done ANY work on the dresser yet.

I'll admit that you pushed, groaned and grunted, sweated and strained plenty. You're physically and mentally exhausted, you're not interested in the dresser at the moment, and right now you just want to snappa cappa brew, crash on the couch, and watch cartoons on TV. But if you've done your Physics homework, you know you haven't technically done any work yet.

In Physics, "Work" is the product of Force times Distance.

Since the dresser hasn't budged yet, the Distahce is zero. So no matter how great the Force may be, it's multiplied by zero, so the Work is zero.
