Answer: D. glacial striations

Explanation:

Glaciers striations are the features formed over the bedrock due to glacier erosion. This occurs due to glacier abrasion that happens during glacier erosion or retreating glacier. This results in the formation of striations into multiple straight parallel lines and scrape marks over the bedrock or ground. These striations appear as grooves.

Answer:

D. Glacial striations

Explanation:

Glacial striations are marks and grooves carved on a rock surface as the materials carried by it abraded the surfaces of the earth.

Answer:

Angle of incline is 20.2978°

Explanation:

Given that;

Gravitational acceleration on a planet a = 3.4 m/s²

Gravitational acceleration on Earth g = 9.8 m/s²

Angle of incline = ∅

Mass of the stone = m

Force on the stone along the incline will be;

F = mgSin∅

F = ma

The stone has the same acceleration as that of the gravitational acceleration on the planet.

ma = mgSin∅

a = gSin∅

Sin∅ = a / g

we substitute

Sin∅ = (3.4 m/s²) / (9.8 m/s²)

Sin∅ = 0.3469

∅ = Sin⁻¹( 0.3469 )

∅ = 20.2978°

Therefore, Angle of incline is 20.2978°

natta225 [31]

Answer:

λ = 437 m.

Explanation:

Since a radio wave is a electromagnetic type of wave, it propagates approximately at the same speed of light in vacuum, 3*10⁸ m/s.
As in any wave, there exist a fixed relationship between the propagation speed, the wavelength and the frequency of the radio wave, as follows:

$c = \lambda* f (1)$
