Answer:

O Intense rain or an earthquake

Explanation:

Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors.

What is the speed of an object that travels 20 meters in 4 seconds?

Iteru [2.4K]

Given:-

Distance covered by the particle (s) = 20 m
Time taken (t) = 4 seconds

To Find: Speed of it.

We know,

v = s/t

where,

v = Speed,
s = Distance &
t = Time taken.

Putting the values,

v = (20 m)/(4 s)

→ v = 5 m/s (Ans.)

Which of the following materials offer the least electrical resistance? Pure water, wood, salt water, glass

Vanyuwa [196]

Salt water offers the least electrical resistance.

Explanation:

Least electrical resistance indicates that any material which readily allows the electric current through itself, and shows more conductivity.

Here pure water doesn't contain any ions, so it is a bad conductor.

Wood and glass are also bad conductors of electricity.

Salt water contains ions, which conducts electricity which means it shows least electrical resistance.

What is the speed of a 50 g rock if its de broglie wavelength is 3.32x10^-34m?

ivann1987 [24]

We can find the momentum of the rock by using De Broglie's relationship:
$p= \frac{h}{\lambda}$
where
p is the momentum
h is the Planck constant
$\lambda$ is the De Broglie's wavelength

By using $\lambda=3.32 \cdot 10^{-34} m$ , we find
$p= \frac{6.6 \cdot 10^{-34} Js}{3.32 \cdot 10^{-34} m}=1.99 kg m/s$

The momentum of the rock is
$p=mv$
where $m=50 g=0.05 kg$ is the mass and v is its velocity. Rearranging the equation, we find the speed of the rock:
$v= \frac{p}{m}= \frac{1.99 kg m/s}{0.05 kg}=39.8 m/s$
