D) convection! here is the reason why :the definition of convection is <span>the concerted, collective movement of groups or aggregates of molecules within fluids (e.g., liquids, gases) and rheids, through advection or through diffusion or as a combination of both of them. So becuase the medal is more convective, this causes it to be heated faster!
Note; this is why we use glass heating plate, so they dont get hot and burn people</span>
You would record this as bonding
Answer:
Explanation:
a)8*7.2=57.6 cm^2
b)8*8=64 m^2
c)3.4*5.2=17.68 mm*2
d)2.6*4.7=12.22 m^2
e)13*5.1=13*5100=66300 m^2
Answer:
Length (L2) = 0.51m
Wavelength of string (∆) = 1.02m
Wavelength of sound produced = 0.7795m
Explanation:
Using the equation L1F1 = L2F2
L1 = 0.68m, F1 = 330Hz, F2 = 440Hz
Therefore, (0.68m)(330Hz) = (L2)(440Hz)
L2 = 0.68m × 330hz/440hz
L2 = 0.51m
0.68m - 0.51m = 0.17m from the but
B. ∆ = 2×length (L2)
∆ = 2(0.51) = 1.02m
C. Frequency (f) = 440Hz
V = ∆f
343m/s =∆×440hz
∆ = 343m/s/440hz
∆ = 0.7795m
Answer: vf = 32 m/s
Explanation: Solution:
Use the formula for acceleration:
a = vf - vi / t
initial velocity vi = 0 since it is at rest.
derive to find vf:
vf = at + vi
= 8.0 m/s² ( 4.0 s ) + 0 m/s
= 32 m/s
