Answer:
i am sorry i have no idea
Explanation:
Answer:
f = 106.3 N
Explanation:
The force applied on the sled must be equal to the static frictional force to move the sled:
Tension Force Horizontal Component = Static Frictional Force
where,
T = Tension = 120 N
θ = angle of rope = 37°
μ = coefficient of static friction = ?
m = mass of children plus sled = 55 kg
g = acceleration due to gravity = 9.81 m/s²
Therefore,
Now, the static friction acting on the mother will be:
<u>f = 106.3 N</u>
You will lose your balance
The answer is D because the mass of H is 1.008 and the mass of Cl is 35.45. When added up the answer is around 36.458. Depending on your periodic table and number of significant figures the values would be different slightly. 36.458 is pretty close to 36.46094 compared to other answers. Hope this helps!
