Answer:

3.9 m

Explanation:

Assuming no energy losses then all kinetic energy is converted to potential energy

$0.5mv^{2}=mgh$ and making h the subject of the formula

$h=\frac {v^{2}}{2g}$ where m is the mass of bike rider and bike, v is the velocity, and g is acceleration due to gravity. Taking g as 9.81 m/s2, v as 8.5 m/s then

$h=\frac {8.5^{2}}{2\times 9.81}=3.946992864\approx 3.9 m$

The only force acting on a 2.9 kg canister that is moving in an xy plane has a magnitude of 7.5 N. The canister initially has a

Elodia [21]

Answer:15.66 J

Explanation:

mass of block $\left ( m\right )=2.9 kg$

Force magnitude=7.5 N

Initial velocity = $3.9\hat{i} m/s$

Final velocity= $5.1 \hat{j} m/s$

Initial Kinetic Energy= $\frac{1}{2}mv^2$

= $\frac{1}{2}\times 2.9\times 3.9^2=22.05 J$

Final Kinetic Energy= $\frac{1}{2}mv^2$

= $\frac{1}{2}\times 2.9\times 5.1^2=37.714 J$

Work Done =Final -Initial Kinetic energy=37.714-22.056=15.66 J

How to understand that an inductor behaves like short circuit and capacitor like an open circuit in steady state in a network?

garik1379 [7]

It depends on the steady-state frequency. At zero frequency an inductor behaves like an open circuit. As the frequency increases, the inductor acts more like an open circuit and a capacitator acts more like a short circuit

8. What current flows through a 1.15 kW electric fire at a potential difference of

Vilka [71]

Answer:

I = 5[amp]

Explanation:

Electrical power is defined as the product of voltage by current.

$P=V*I$

where:

P = power = 1150 [W]

V = voltage = 230 [V]

I = current [amp]

Now replacing:

$1150=230*I\\I=1150/230\\I=5[amp]$

A 15 [amp] fuse must be used. Always the fuse must be larger than the operating current, to protect the equipment from very high currents. above 15 [amp]
