Answer:
Sutures are nonmoving joints that connect bones of the skull
Explanation:
These joints have serrated edges that lock together with fibers of connective tissue.
Answer:
2.27kg
Explanation:
The Potential energy gained = Force gravity× Height
Force gravity on the ball is GPE/ height
56.8/2.5=22.72N
the mass = 22.72/10= 2.27kg
Answer:
The resistance is found to be 6Ω
The current is found to be 0.66 A
Explanation:
The resistance of a conductor in terms of its dimensions is given as:
R = ρL/A
where,
R = resistance = ?
ρ = resistivity = 3 x 10⁴ Ω.m
L = Length = 4 mm = 0.004 m
A = Cross-sectional area = 0.2 mm² = 0.2 x 10⁻⁶ m²
Therefore,
R = (3 x 10⁴ Ω.m)(0.004 m)/(0.2 x 10⁻⁶ m²)
<u>R = 6 Ω</u>
Now, the potential difference between both ends of the resistor is:
ΔV = 16 V - 12 V = 4 V
Now, from Ohm's Law:
V = IR
I = V/R
I = 4 V/ 6 Ω
<u>I = 0.66 A</u>
Answer:
mass 20 times of an amazing and all its motion
Been a while since i've done a problem like this so i might be wrong in the "work" aspect
your system starts with 1200J
you add 700J of heat-
add 700 to 1200
1200+700
and your system does 400J of work
since work is being done by the system, the energy is leaving the system hence you subtract
1900-400
the result is then 1500
