Geothermal and nuclear energy are derived from radioactive materials.
Wave energy, from the ocean, is derived from winds blowing over the ocean, which are derived from the Sun's uneven heating of the earth.
Biomass energy is from plants, which get energy through photosynthesis, derived from the Sun.
Answer:
V_c=5.037 m/s
Explanation:
SOLUTION:
applying the conversation of energy, taking the datum at B
V_b=(m_c+m_b)gh_a=(3+0.5)*9.81*0=0 J
V_b=4.95 m/s
applying the conversation of linear momentum,
(m_c+m_b)V_b=m_c*V_c+m_b*V_b
V_b=6*V_c-34.66 (1)
utilising the relative velocity relation,
V_b/c=V_b-V_c
V_b=0.6-V_c (2)
from (1) (2)
6*V_c-34.66=0.6-V_c
7*V_c=35.26
the final velocity of the cart is
V_c=5.037 m/s
into (2)
V_b=0.6-V_c
V_b=0.6-5.037
= 4.437

Correct option is B.
Answer:
5.01×10⁴ J.
Explanation:
Applying,
q = Cm....................... Equation 1
Where q = amount of heat needed to melt the ice, m = mass of the ice, C = specific latent heat of ice.
From the question,
Given: m = 150 g = (150/1000) kg = 0.15 kg, C = 3.34×10⁵ J/kg
Substitute these values into equation 1
q = (0.15×3.34×10⁵)
q = 0.501×10⁵ J
q = 5.01×10⁴ J.
