Ocean acidification impacts corals in what major way?

1 answer:

5 0

Many marine species, including coral, need calcium carbonate to build their protective shells and exoskeletons. Without it, shells grow slowly and become weak. Therefore, ocean acidification impacts Coral reefs with breakable, slow-growing corals erode more quickly than they accrete.

A particle with charge q and momentum p, initially moving along the x-axis, enters a region where a uniform magnetic field* B=(B

VMariaS [17]

Answer:

Magnitude of momentum = q × B0 × [d^2 + 2L^2] / 2d.

Explanation:

So, from the question, we are given that the charge = q, the momentum = p.

=> From the question We are also given that, "initially, there is movement along the x-axis which then enters a region where a uniform magnetic field* B = (B0)(k) which then extends over a width x = L, the distance = d in the +y direction as it traverses the field."

Momentum,P = mass × Velocity, v -----(1).

We know that for a free particle the magnetic field is equal to the centrepetal force. Thus, we have the magnetic field = mass,.m × (velocity,v)^2 / radius, r.

Radius,r = P × v / B0 -----------------------------(2).

Centrepetal force = q × B0 × v. ----------(3).

(If X = L and distance = d)Therefore, the radius after solving binomially, radius = (d^2 + 2 L^2) / 2d.

Equating Equation (2) and (3) gives;

P = B0 × q × r.

Hence, the Magnitude of momentum = q × B0 × [d^2 + 2L^2] / 2d.

Which statement would be a valid argument in favor of using nuclear power? There are few negative impacts from mining the fuel.

fgiga [73]

Okay so, lets use the process of elimination here.

<span>A)There are few negative impacts from mining the fuel.
B)Reactors are safe from natural disasters.
C)There are little to no waste products from fission.
D)Nuclear power does not contribute greenhouse gases.

First off, we know B cannot be correct, seeing as how reactors are fragile and are damaged easily by Japan's earthquakes. So we can eliminate B from the choices. We then can eliminate C, since fission creates high levels of nuclear waste, so that leaves us with just A, and D. We can then eliminate A since uranium is radioactive, there is always a chance for negative effects.

So, the correct answer is D</span>

A car with mass mc = 1490 kg is traveling west through an intersection at a magnitude of velocity of vc = 9.5 m/s when a truck o

icang [17]

Answer:

v= - 4.507 i - 2.363 j

Explanation:

Given that

mc= 1490 kg

vc= 9.5 m/s ( - i)

mt= 1650 kg

vt = 6.4 m/s ( -j)

There is any external force so linear momentum will remain conserve.

Lets take final speed is v.

mc .vc + mt . vt = ( mc+mt) v

1490 x 9.5 ( - i) + 1650 x 6.4 ( -j) = ( 1490+1650) v

14,155 ( -i) + 10,560 ( - j) = 3140 v

v= - 4.507 i - 2.363 j

BRAINLIEST WILL BE MARKED FOR THE FIRST ANSWER

Answer:

98.4 N

Explanation:

Given that the body weighs 800 N on earth.

Thus,

Weight = mass x acceleration due gravity

i.e W = mg

800 = m x 10

m = $\frac{800}{10}$

= 80 kg

The mass of the body is 80 kg.

To be able to determine its weight on the planet, we have to first calculate the gravitational pull of the planet.

But,

g = $\frac{GM}{r^{2} }$

Where: G is the Newton's universal gravitation, M is the mass of the planet and r is the radius of the planet.

g = $\frac{6.674*10^{-11} *2.986*10^{24} }{(12.742*10^{6})^{2} }$

= $\frac{1.9929*10^{14} }{1.6236*10^{14} }$

= 1.2275

g = 1.23 m/ $s^{2}$

Thus,

Weight of the body on the planet = mg

= 80 x 1.23

= 98.4 N

The weight of the body on the planet is 98.4 N
