It seems that you have missed the necessary options for us to answer this question, but anyway, here is the answer. The type of machine that a wire cutter pliers is classified is a simple machine. When we say simple machine, this is the type of machine that is considered basic wherein you need to apply force for it to function. Hope this helps.
Answer:
The net force is 26.52 N
Explanation:
Given that,
Volume of balloon = 2.1 L
Density of air = 1.29 kg/m³
Mass = 1.3 g
Density of helium 
(a). We need to calculate the buoyant force on the balloon
Using formula of buoyant force

Put the value into the formula


(b). We need to calculate the net force
Using formula of net force



Hence, The net force is 26.52 N.
The force of gravity is the only force that keeps a pendulum in motion. both the force increases the speed of the pendulum on the downswing and decreases it's speed on its upswing.
1) Increasing the current flow
2) Increasing the number of coils
3) Passing an 'iron core' through the coil of the electromagnet
Answer:
t = 1,144 s
Explanation:
The simple pendulum consists of an inextensible string with a mass at the tip, the angular velocity of this is
w = √( L / g)
The angular velocity is related to the frequency and period
w = 2π f
f = 1 / T
w = 2π / T
Let's replace
2π / T = √ (L / g)
T = 2π √ (g / L)
Let's calculate
T = 2π √ (9.81 / 18.5)
T = 4,576 s
The definition of period in the time it takes the ball to come and go to a given point (a revolution) in our case we go from the end to the middle point that is a quarter of the path
t = T / 4
t = 4,576 / 4
t = 1,144 s
