Question

M=34 кг F=260H g=10H/кг ŋ=?

Answer 1

Ответ:

F=Mg. M=F/g. M=40/10=4кг

Answer 2

It appears you're providing values for mass (M), force (F), and gravitational acceleration (g), and you want to calculate the efficiency (ŋ) of a system. Efficiency is typically calculated using the following formula:

ŋ = (Useful Output Energy or Work) / (Input Energy or Work)

In your case, it seems you want to calculate efficiency in the context of lifting an object (mass) against gravity (force due to gravity). The useful output work, in this case, is the work done against gravity to lift the mass.

Work done (W) = Force (F) * Distance (d)

Where:

• Mass (M) = 34 kg
• Force due to gravity (g) = 10 N/kg (Note: The units for 'g' should be in newtons per kilogram, not hours per kilogram.)
• Force (F) = 260 N

Now, let's calculate the work done to lift the mass:

W = F * d

To find 'd', you'll need more information about the distance over which the force is applied. Once you have the distance (in meters), you can calculate the work done.

After calculating the work done (Useful Output Work), you can calculate the efficiency ŋ using the formula mentioned earlier:

ŋ = Useful Output Work / Input Work

If you provide the distance (d), I can help you calculate the efficiency.
