What landforms form at convergent boundaries where two oceanic plates collide?

They are formed when two plates collide, either crumpling up and forming mountains or pushing one of the plates under the other and back into the mantle to melt. Convergent boundaries form strong earthquakes, as well as volcanic mountains or islands, when the sinking oceanic plate melts.

Two cars are traveling at the same speed of 27 m/s on a curve thathas a radius of 120 m. Car A has a mass of 1100 kg and car B h
Lera25 [3.4K]

Answer:

a_{cA} = 6.075  m/s²

a_{cB} = 6.075  m/s²

F_{cA} = 6682.5 N

F_{cB} = 9720 N

Explanation:

Normal or centripetal acceleration measures change in speed direction over time. Its expression is given by:

a_{c} = \frac{v^{2} }{r}  Formula 1

Where:

a_{c} : Is the normal or centripetal acceleration of the body  ( m/s²)

v: It is the magnitude of the tangential velocity of the body at the given point

.(m/s)

r: It is the radius of curvature. (m)

Newton's second law:

∑F = m*a Formula ( 2)

∑F : algebraic sum of the forces in Newton (N)

m : mass in kilograms (kg)

Data

v_{A} = 27 \frac{m}{s}

v_{B} = 27 \frac{m}{s}

m_{A} = 1100 kg

m_{B} = 1600 kg

r= 120 m

Problem development

We replace data in formula (1) to calculate centripetal acceleration:

a_{cA} = \frac{(27)^{2} }{120}

a_{cA} = 6.075  m/s²

a_{cB} = \frac{(27)^{2} }{120}

a_{cB} = 6.075  m/s²

We replace data in formula (2) to calculate  centripetal  force Fc) :

F_{cA} = m_{A} *a_{cA} = 1100kg*6.075\frac{m}{s^{2} }

F_{cA} = 6682.5 N

F_{cB} = m_{B} *a_{cB} = 1600kg*6.075\frac{m}{s^{2} }

F_{cB} = 9720 N

A boat has a mass of 6800 kg. Its engines generate a drive force of 4100 N due west, while the wind exerts a force of 800 N due
mezya [45]

Answer:

The boat's acceleration are:  a= 0.3 m/s² in west direction.

Explanation:

Fm= 4100 N

Fwi= 800 N

Fwa= 1200 N

Fm - Fwi - Fwa= m *a

clearing a:

a= 0.3 m/s²

A 82-kg fisherman in a 112-kg boat throws a package of mass m = 15 kg horizontally toward the right with a speed of vi = 4.8 m/s
abruzzese [7]

Answer:

0.37 m/s to the left

Explanation:

Momentum is conserved.  Initial momentum = final momentum.

m₁ u₁ + m₂ u₂ = m₁ v₁ + m₂ v₂

Initially, both the fisherman/boat and the package are at rest.

0 = m₁ v₁ + m₂ v₂

Plugging in values and solving:

0 = (82 kg + 112 kg) v + (15 kg) (4.8 m/s)

v = -0.37 m/s

The boat's velocity is 0.37 m/s to the left.

If you walk across a nylon rug and then touch a large metal object such as a doorknob you may get a spark and a shock. Why does
k0ka [10]

Answer:

Explanation:

  • You are more likely to be shocked during dry days than humid days because during humid days more water is in the air, and water being a good conductor helps the air absorb some of those charges from you, while during dry days there is less water in the air and hence the charges build up since they are not absorbed.
  • You are less likely to be shocked when you touch a small metal object because smaller metal objects like a paper clip have less space to accept net charge.
