A car has negative acceleration. What information can you infer from this?

Answer

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

Erosion is the geological process in which earthen materials are worn away and transported by natural forces such as wind or water. A similar process, weathering, breaks down or dissolves rock, but does not involve movement.

Physical weathering is caused by the effects of changing temperature on rocks, causing the rock to break apart. The process is sometimes assisted by water. ... Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart.

Swiftly moving water. Rapidly moving water can lift, for short periods of time, rocks from the stream bottom. ...

Ice wedging. Ice wedging causes many rocks to break. ...

Plant roots. Plant roots can grow in cracks.

the erosion or disintegration of rocks, building materials, etc., caused by chemical reactions (chiefly with water and substances dissolved in it) rather than by mechanical processes.

Carbonation. When you think of carbonation, think carbon! ...

Oxidation. Oxygen causes oxidation. ... or

Hydration. This isn't the hydration used in your body, but it's similar. ...

Biological weathering is weathering caused by plants and animals. Plants and animals release acid forming chemicals that cause weathering and also contribute to the breaking down of rocks and landforms. Chemical weathering is weathering caused by breaking down of rocks and landforms.

Burrowing animals like shrews, moles, earthworms, and even ants contribute to biological weathering. ...

When animals like birds forage for seeds and earthworms, they create holes and erode the upper surface of the soil, thus, contributes to weathering.

rabbits and other burrowing animals can burrow into a crack in a rock, making it bigger and splitting the rock. You may have seen weeds growing through cracks in the pavement.

In an inelastic collision involving an isolated system, the final total momentum is

Aleksandr-060686 [28]

Answer: B) exactly the same as the initial momentum.

Explanation:

An inelastic collision occurs when the elements that collide remain together after the collision, and althogh the kinetic energy is not conserved because is transformed into other kinds of energy (thermal energy, for example), the linear momentum does.

This means the initial momentum before the collision will be equal to the final momentum after the collision:

$p_{o}=p_{f}$

Consider a metal single crystal oriented such that the normal to the slip plane and slip direction are at angles of 60° and 35°,

Vedmedyk [2.9K]

Answer:

19.5324 MPa

Explanation:

Information provided

Angle between the normal to the slip plane with tensile axis, $\alpha=60^{o}
$

Angle by slip direction with tensile axis, $\beta=35^{o}$

Critical resolved shear stress, $\tau_{c}=8 MPa$

Applied stress $\sigma=12 MPa$

Shear stress at slip plane

$\tau=\sigma cos\alpha cos\beta$

$\tau=12cos60^{o}cos35^{o}=4.915 MPa$

$\tau$ hence crystal won’t yield

Applied stress, $\sigma$ for crystal to yield is given by

$\sigma=\frac {\tau_{c}}{cos\alpha cos\beta}$

$\sigma=\frac {8}{cos60cos35}=19.53239342 MPa$

$\sigma=19.5324 MPa
$

____________ is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

velikii [3]

Volt is the unit that measures the pressure or force that pushes the flow of electrons forward through a conductor.

When there is a circuit having a cell / battery , that cell/battery forms an electric field due to difference in voltages , and set a voltage of value equals to the difference in the voltage of two end of that cell/ battery . Because of which a electric field got set up in the conductor , which pushes electron to move inside the conductor . Unit of voltage is volt .

VOLT - A unit of electrical pressure (or electromotive force) which causes current to flow in a circuit. One volt is the amount of pressure required to cause one ampere of current to flow against one ohm of resistance. VOLTAGE - That force which is generated to cause current to flow in an electrical circuit.

Voltage is the pressure from an electrical circuit's power source that pushes charged electrons (current) through a conducting loop, enabling them to do work such as illuminating a light. In brief, voltage = pressure, and it is measured in volts (V).
