Answer:
delay or stifle the emergence of the perspective
Answer:
1.022 x 103 N.m
Explanation:
Solution
Given:
The weight of the block of mass m₂ is :
w₂ = m₂*g
Where
w₂ = 39 x 9.8 = 382.2 N
Then,
The weight of the block of mass m₁
w₁= m₁*g;
so,
w₁ = 12 x 9.8 = 117.5 N
Thus,
The tension wrapped in cord on drum (80 cm) T₁ = F - w₁
Now,
T₁ = 1200 - 117.5
T₁ = 1082.5 N
The tension wrapped in the cord on drum (41 cm) T₂ = w₂;
T₂ = 382.2 N
Hence,
We calculate net torque on the center of the drum:
The net torque = T₁ x 0.8 + T₂ x 0.41;
= 1082.5 x 0.8 + 382.2 x 0.41;
= 1.022 x 103 N.m
Therefore, the resulting torque applied to the system is 1.022 x 103 N.m
Well, we know that mass is conserved, so the missing 4 kg couldn't
just disappear. It had to go somewhere.
It may have left the burning log in the form of hot gases and smoke particles.
Answer:
the process of that happening is called Dissolving
the substance that is dissolved is called
Solute
Answer:
3.1 s
Explanation:
we can assume that this motion has a horizontal projectile motion.
projectile motion happens when an object is subjected to only gravity. Gravity acts to influence the vertical motion of the projectile, it makes a vertical acceleration.
The horizontal motion of the projectile is the result of the constant velocity of the object.We assume no acceleration in the horizontal direction.
applying motion equations
where
s - distance
u - initial velocity
a-acceleration
t - time
s = ut + (1/2)at²
→ 165 = 50t + 0 (as no acceleration is in horizontal direction)
t = 3.1 s
