Answer:
it is a interspecific competition
Explanation:
i just took a test with this question
The currents responsible for powering the movement of tectonic plates is convection currents which occur in the mantle. As the hotter, less dense liquid rises it displaces the cooler more dense liquid which moves the tectonic plates out of allignment
Answer:
A. T=126N
B. T=63N
Explanation:
To determine the tension in each given blocks, we first determine the acceleration of each block. It obvious that each mass will move with the same acceleration since the string connecting them is massless.
Hence using the equation of force we have
F=ma
Where m=total mass of blocks,
a=acceleration
F= force applied in this case the tension in the string.
For a 134 identical masses with an applied force of 134N, the acceleration of each mass can be computed as
134=134m*a
a=134/134m
a=(1/m )m/s²
a. To calculate the tension in the string between the 126 and 127 block, we use the equation below
T=ma
Since the number of blocks before the string is 126, we multiply the mass of each block by 126.
Hence the tension can be computed as
T=126m*a
Since a=1/m then
T=126m*1/m
T=126N
B.To calculate the tension in the string between the 63 and 64 block, we use the equation below
T=ma
Since the number of blocks before the string is 63, we multiply the mass of each block by 63.
Hence the tension can be computed as
T=63m*a
Since a=1/m then
T=63m*1/m
T=63N
Answer:
322 kJ
Explanation:
The work is the energy that a force produces when realizes a displacement. So, for a gas, it occurs when it expands or when it compress.
When the gas expands it realizes work, so the work is positive, when it compress, it's suffering work, so the work is negative.
For a constant pressure, the work can be calcutated by:
W = pxΔV, where W is the work, p is the pressure, and ΔV is the volume variation. To find the work in Joules, the pressure must be in Pascal (1 atm = 101325 Pa), and the volume in m³ (1 L = 0.001 m³), so:
p = 60 atm = 6.08x10⁶ Pa
ΔV = 82.0 - 29.0 = 53 L = 0.053 m³
W = 6.08x10⁶x0.053
W = 322x10³ J
W = 322 kJ
