Explain: Is it possible to convert milliliters to liters? How about milliliters to grams?
Advocard [28]

Answer:

yes, it is possible

Explanation:

To convert milliliters to liters, we divide by 1000.

To convert milliliters to grams, we multiply the volume (in ml) by the density (in g).

Which statement accurately describes the motion of the objects in the ticker tape above?
Fynjy0 [20]

Answer: "One object speeds up before it slows to a stop "

(the top one)

Explanation:

Ok, first a little recall on how to read this type of graph.

If the points are far apart, the object is moving fast.

If the points are close together, the object is moving slow.

If the distance between the points changes then the velocity of the object changes, which means that the object is accelerated.

If we have a lot of points clustered in one location, then the object is not moving.

We can see:

The top object starts slow, then it increments the speed, then it slows down again, and then it comes to stop.

The bottom object starts fast, and it slows down.

then:

"One object speeds up before it slows to a stop "

This describes the motion of the top object, this is the only correct option that describes one of the graphs.

What happens overtime to rocks that are stressed
malfutka [58]

Answer:

Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.

A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.

Compression squeezes rocks together, causing rocks to fold or fracture (break) (Figure below). Compression is the most common stress at convergent plate boundaries.

Oceanographers use submerged sonar systems, towed by a cable from a ship, to map the ocean floor. In addition to their downward
KATRIN_1 [288]

Answer:

Tension in the cable is T = 16653.32 N

Explanation:

Give data:

Cross section Area A = 1.3 m^2

Drag coefficient CD = 1.2

Velocity V = 4.3 m/s

Angle made by cable with horizontal  =30 degree

Density \rho \ of\  water= 1000 kg/m3

 Drag force FD is given as

F_{D} = \fracP{1}{2} \rho v^{2} C_{D} A

        = 0.5\times 1000\times 4.32\times  1.2\times 1.3

Drag force = 14422.2 N acting opposite to the motion

As cable made angle  of 30 degree with horizontal  thus horizontal component is take into action to calculate drag force

TCos30 = F_D

T = \frac{F_D}{cos30}

T =\frac{ 14422.2}{cos 30}

T = 16653.32 N
