B, because gold is the most malleable substance of all.
Answer:
No getting rid of fossil fuel is not at all possible.
Explanation:
Dream of 100% renewable energy is possible through electrification and use of energy from sun, water and wind. Since, the high production cost of power plant for extracting energy from these sources in itself is a big challenge and hence decarbonized energy in current scenario is not realistic.
Answer:
Explanation:
F = qvB
Where F equal to the magnetic force on the particle.
q = charge on the particle
v = velocity of the particle
B =Magnetic field
F = 0.520N
q = 7.4 μC = 7.4×10-⁶C
v = 3×10⁵m/s
B= ?
B = F/qv
B = 0.520/(7.4×10-⁶ ×3×10⁵)
B = 0.234T.
Answer:
p = 1.2 kg-m/s
Explanation:
The question is, "An object of mass 0.5kg is moving along a rectilinear path with constant acceleration of 0.3m / s2. If it started from rest and the magnitude of its momentum in kg * m / s after 8s is".
Mass of the object, m = 0.5 kg
Acceleration of the object, a = 0.3 m/s²
We need to find the momentum after 8 seconds.
We know that,
i.e.
p = mat
So,
So, the momentum of the object is 1.2 kg-m/s.
Answer:
True
Explanation:
Insulators are the material that does not allow electricity to pass easily through them. The reason behind using an insulator as a protective layer on an electrical wire or appliances is that they show good resistance to electricity. That prevents us from getting an electrical shock. And rubber and plastics are good examples of the insulator.
Hence our statement is true.
