Answer:
115kg
Explanation:
Given parameters:
Weight of the refrigerator = 1127N
Unknown:
Mass of the refrigerator = ?
Solution:
Weight is the force that acts on an object due to gravity;
Weight = mass x acceleration due to gravity
Acceleration due to gravity = 9.8m/s²
Now, input the parameters and solve for mass;
1127 = mass x 9.8
mass = = 115kg
Isn't that just normal body tissue?
The answer is B. natural gas
Answer:
b) a horse pulls a wagon at a constant velocity
Explanation:
As we know that ,work done is the dot product of force vector and displacement vector.
W= F.d
W=work
F=Force
d=Displacement
We also know that
F = m a
m= mass ,a = acceleration
When velocity is constant then rate of change in the velocity will be zero,then we can say that acceleration will be zero.
When a= 0 Then F= 0
W= F.d ( F=0)
W = 0
Therefore option b i correct because horse is going with constant velocity.
Answer:
A tornado can, surprisingly, cause a supercell, so the answer would be C.) tornado
Explanation:
When cold, dry, and polar air meet warm, moist tropical air, the atmosphere becomes unstable causing a supercell.
Final Answer:
C.) tornado
