Answer:
a human that walks on earth
Explanation:
Force of attraction between one atom and another within a compound formed by sharing of electrons or the loss and gain of electrons this is a bond
Answer:
Q = 50.25 [J]
Explanation:
To solve this problem we must use the following equation that relates the temperature change with the mass and with the specific heat.
Q = m*Cp*(DT)
where:
Q = energy in form of heat [J]
m = mass = 5 [g] = 0.005 [kg]
Cp = specific heat = 1005 [J/kg*°C]
DT = temperature change = 10 [°C]
Now replacing:
Q = 0.005*1005*10
Q = 50.25 [J]
Answer:
v = 0.84 m/s
Explanation:
given,
R = 12 cm
M (mass of pulley )= 520 g
m (mass of block)= 20 g
s = 50 cm = 0.5 m
using conservation of energy
Potential energy = Kinetic energy

and v = r ω





v = √0.7
v = 0.84 m/s
Answer:
4 m/s
Explanation:
Given:
Δx = 39 m
a = 6 m/s²
t = 3 s
Find: v₀
Δx = v₀ t + ½ at²
39 m = v₀ (3 s) + ½ (6 m/s²) (3 s)²
v₀ = 4 m/s
