Water flowing in a stream erodes through abrasion, saltation, traction of material along the river bed etc, cutting down into the ground mostly just below it, creating a V shaped valley.
Ice in glaciers scours its way through the rock material beanth it. Because of this bulldozer kind of effect, it creates a U shaped valley.

Answer:
I believe its true
Explanation:
After completing its mission, Juno will be intentionally deorbited into Jupiter's atmosphere. Juno's mission is to measure Jupiter's composition, gravity field, magnetic field, and polar magnetosphere
I would choose the first and second one because the question is asking you a specific question that they try & look at
Answer:
0.75 NC⁻¹
Explanation:
Electric field intensity ( or strength of the electric field ) is the force per a 1 C charge,
So, Force (F) = Electric field intensity(E) × Charge (q)
F = E×q ⇒ q = F/E
= 4.5×10⁻⁴/6×10⁻⁴ = 0.75 NC⁻¹
According to cool om's law electric fields are generated due to charges. When charges are same there is a repulsive force acted on both charges. When charges are opposite there is a attraction force acted on both charges.
According to cool om's law,
F =G×q1×q2 / r²
F = force exerted of two charges
q1 , q2 = charges
r = distance between two charges
And also Electric field intensity is a vector which has a magnitude and direction both. Direction is depending on a charge and the sign of the charge
