I think it would be a bowling ball because it’s harder to stop than a golf ball.

I would Say the Bowling Ball, Would have more momentum, Because of Newtons 3rd Law.

I hope I helped

The slowest line is the solid line and the fastest is the dotted line that crosses the solid line
for future reference you just need to find the slope or the line which is traveling most vertical

A pilot drops a bomb from a plane flying horizontally with constant velocity. When the bomb hits the ground, the horizontal loca

polet [3.4K]

Answer: The horizontal location of the plane will BE OVER THE BOMB

Explanation:

As soon as the bomb was dropped, the bomb will fall under gravity (free fall) and the location of the plane continues to increase horizontally till the bomb reaches the ground which is a falling distance to be travelled by the bomb at 9.8m/s²

Electrolytes are considered ________ when placed in a solution and allow for adequate conduction of ________ charges.

DedPeter [7]

Answer:

Electrolytes are considered ions when placed in a solution and allow for adequate conduction of particle charges.

Explanation:

Electrolytes are substances that, when are dissolved in solution, separates into electrical positive charges (cations) and electrical negative charges (anions) which are known as ions.

These ions have an adequate capacity to conduct particle charges and, therefore electricity.

Sodium, calcium, phosphate and potassium, are examples of electrolytes.

<u>Hence, the correct answer is:</u>

Electrolytes are considered ions when placed in a solution and allow for adequate conduction of particle charges.

I hope it helps you!

A beaker of mass 1.3 kg containing 2.8 kg of water rests on a scale. A 3.7 kg block of a metallic alloy of density 4600 kg/m3 is

Oksana_A [137]

1) Force read on the upper scale: 33.4 N

2) Force read on the lower scale: 43.0 N

Explanation:

The reading on the upper scale is equal to the net force acting on the block of metallic alloy. The net force is given by:

$F=W-B$ (1)

where

W is the weight of the block (downward)

B is the buoyant force (upward)

The weight of the block is given by

$W=mg$

where m = 3.7 kg is the mass of the block and $g=9.8 m/s^2$ is the acceleration of gravity.

The buoyant force is given by

$B=\rho_w V g$

where

$\rho_w=1000 kg/m^3$ is the water density

V is the volume of the block

The volume of the block can be written as

$V=\frac{m}{\rho_b}$

where $\rho_b=4600 kg/m^3$ is the density of the block.

Substituting everything into eq.(1), we find:

$F=mg-\rho_w \frac{m}{\rho_b}g=(3.7)(9.8)-(1000)\frac{1.3}{4600}(9.8)=33.4 N$

Here we want to find the force on the lower scale.

The force on the lower scale is equal to the difference between the total weight of the system (given by the weight of the beaker + the weight of the water + the weight of the block) and the upper net force exerted on the upper scale, therefore:

$F' = m_B g + m_wg+m_b g - F$
