Answer:  Is the movement of sediment by gravity.

Mass wasting is the movement of sediments generate due to the mass movement of rock, soil or other debris from a hilly or slopy region downwards due to the effect of gravity. This effect can be highly be observed during landslides. Agents like wind and water also promote this effect.

Mass wasting is the movement of sediment by gravity transports. Meaning the earth’s outer crust is being ‘wasted’ away on a ‘massive’ scale and falling to lower elevations. It is also a type of erosion and can make changes to the side of the mountain.

When the voltage is high, 100v, how does the filament appear?
Nat2105 [25]
<span>when voltage is high say 100V than the light will be a lot dimmer than design because the light is usually designed to be operated at 240V . If the supply voltage to the bulb is 100V, the filament dissipates 34.7W power and thus the temperature of the filament will be less and hence the bulb does not produce so much light .</span>

topjm [15]

Answer:

\alpha=214.8 rad/s^2

Explanation:

We are given that

F_1=137 N

F_2=43 N

Net force=F=F_1-F_2=137-43=94 N

Mass,m=1.21 kg

Radius,r=0.723 m

We have to find the magnitude of its angular acceleration.

Moment of inertia ,I=\frac{1}{2}mr^2

Substitute the values

Torque ,\tau=I\alpha

F_{net}\times r=\frac{1}{2}mr^2\alpha

\alpha=\frac{2F_{net}}{mr}

\alpha=\frac{2\times 94}{1.21\times 0.723}

\alpha=214.8 rad/s^2

Answer:

668 bright fringes

Explanation:

t = Thickness = 0.2 mm

\lambda = Wavelength = 600 nm

m = Number of fringes

We have the fringe width relation

2t=\left(m+\frac{1}{2}\right)\lambda\\\Rightarrow m=\dfrac{2t}{\lambda}-\dfrac{1}{2}\\\Rightarrow m=\dfrac{2\times 0.2\times 10^{-3}}{600\times 10^{-9}}-\dfrac{1}{2}\\\Rightarrow m=666.166\approx 667

So, total number of fringes will be including m = 0 is 1+667=668

The maximum potential energy of a spring system (mass 15 kg, spring constant 850 N/m) is 6.5 J. a) What is the amplitude of the
Bumek [7]

Answer:

a) 0.124 m

b) 0.93 ms⁻¹

c) 0.5 k A² cos ² ( ωt )  

Explanation:

1) Potential energy = U = 0.5 k A² , where A is the amplitude and k = 850 N/m is the spring constant.

0.5 ( 850) (A² ) = 6.5

⇒ A = 0.124 m = Amplitude.

b) From energy conservation,  0.5 m v² =  6.5

⇒ speed = v = 0.93 ms⁻¹

c) If x = A cos ωt ,

Potential energy = 0.5 k A² = 0.5 k A² cos ² ( ωt )
