Either convection or thermal energy
If only I was smart then I could help you :/ no but like for real im madddd dumb sorry :(
Answer:
minimum interface length = 1.36 mm
Explanation:
given data
weight of the bug =
N
solution
we will apply here Surface Tension formula that is
Surface Tension ,σ = Force ÷ length ........................1
and we consider here surface tension for water is 7.34 ×
N/m
so that here minimum interface length needed to support the bug is
minimum interface length = Force ÷ σ
minimum interface length =
÷ 7.34 ×
minimum interface length = 1.36 mm
In order to create a charged object you need to transfer electrons either away or to the object by induction, conduction, or friction
Induction is without contact(like bringing a charged object to a electroscope charges the leaves at the bottom)
Conduction is with contact(like the previous answer, wore touching transfers the charge from a source to the object)
Friction(rubbing a balloon on wool)
Answer:
option C
Explanation:
Let mass of the bullet be m and velocity be v
mass of gun be M and bullet be V
now,
using conservation of momentum for gun 1
(M+m) V' = 2 mv + 3 MV
V' = 0
3 M V = - 2 mv
momentum of gun 1 =- 2 mv---------(1)
now for gun 2
(M+m) V' = mv + MV
V' = 0
M V = - mv
momentum of gun 1 = -mv-----------(2)
dividing equation (1) by (2)


the correct answer is option C
