<h3>Answer;</h3>

Accretionary wedge

<h3>Explanation;</h3>

An accumulation of different sedimentary and metamorphic rocks combined with scraps of ocean crust is called accretionary wedge.
Accretionary wedge results from the sediments that are accreted onto the subducting tectonic plate at a convergent plate boundary.
At the abduction zone, the lower plate scrapes along the bottom of the overriding plate as it enters the earth, an action which erodes material that consists of rock and sediment that then accumulate onto the overriding plate in an accretionary wedge.

Accretionary wedge. The accretionary wedge is formed from several sediments: marine sediments, but also erosional materials from volcanoes. ocean floor basalts, volcanic island masses, pelagic sediments, trench sediments and other materials transported by gravity. All these sediments are in the non-subducting tectonic plate of the Earth.

Answer:

$1.6726\cdot 10^{-27} kg$

Explanation:

The three main particles that make an atom are:

- Proton: its mass is $1.6726\cdot 10^{-27} kg$ , it carries an electric charge of +e ( $e=1.6\cdot 10^{-19}C$ ), and it is located in the nucles of the atom

- Neutron: its mass is $1.6749 \cdot 10^{-27}kg$ , it carries no electric charge, and it is also located in the nucleus of the atom

- Electron: its mass is $9.1094 \cdot 10^{-31}kg$ , it carries an electric charge of -e ( $e=1.6\cdot 10^{-19}C$ ), and it is located outside the nucleus

The two pucks of equal mass did not move linearly (they came to a stop) after the collision due to the conservation of linear mo

weeeeeb [17]

Compared to the pucks given, the pair of pucks will rotate at the same rate.

Answer: Option A

Explanation:

The law of conservation of the angular momentum expresses that when no outer torque follows upon an article, no difference in angular momentum will happen. At the point when an item is turning in a shut framework and no outside torques are applied to it, it will have no change in angular momentum.

The conservation of the angular momentum clarifies the angular quickening of an ice skater as she brings her arms and legs near the vertical rotate of revolution. In the event, that the net torque is zero, at that point angular momentum is steady or saved.

By twice the mass yet keeping the speeds unaltered, also twice the angular momentum's to the two-puck framework. Be that as it may, we likewise double the moment of inertia. Since $L=I \times \omega$ , the turning rate of the two-puck framework must stay unaltered.

Find the torque required for the shaft to transmit 40 kW when (a) The shaft speed is 2500 rev/min. (b) The shaft speed is 250 re

Luba_88 [7]

Answer:

(a) 152.85 Nm

(b) 1528.5 Nm

Explanation:

According to the formula of power

P = τ ω

ω = 2 π f

(a) f = 2500 rpm = 2500 / 60 = 41.67 rps

So, 40 x 1000 = τ x 2 x 3.14 x 41.67

τ = 152.85 Nm

(b) f = 250 rpm = 250 / 60 = 4.167 rps

So, 40 x 1000 = τ x 2 x 3.14 x 4.167

τ = 1528.5 Nm
