Two children, A and B, fire identical 10.0g all bearings from a catapult. the elastic band of each catapult extended by 0.10m an

d then released to fire the ball bearings. Child A's elastic band has a spring constant of 144N/m. calculate the energy transferred to the kinetic energy store of the child A's ball bearing.
thanks soo much (:

Tasya [4]

Answer:1.04 N

Explanation:

Given

Gravitational Force on the Platter is 5 N

Tray makes an angle of \theta =12^{\circ}

This gravitational Force has components along and Perpendicular to Platter

Perpendicular Force W_p=W\cos \theta

W_p=5\times \cos 12=4.89 N

Along the Tray

W_{along}=W\sin \theta

W_{along}=5\times \sin 12=1.04 N

Thus 1.04 N is the magnitude of force that will cause Platter to slide down

Which description of energy changes in nuclear reactions is correct?
Kryger [21]
The answer for this question is letter "B.Fission releases energy, and its products have greater stability."

Fission and Fusion are both nuclear reactions that when they release energy, they make the nuclei more stable. So among the choices, option B is the most fitting for the definition.

How are weather from ice and plants different from weathering from wind and water?
DENIUS [597]
“Weathering is the breaking down of rocks, soil and minerals as well as wood and artificial materials through contact with the Earth’s atmosphere, biota and waters. Weathering occurs in situ, roughly translated to: “with no movement”, and thus should not be confused with erosion, which involves the movement of rocks and minerals by agents such as water, ice, snow, wind, waves and gravity and then being transported and deposited in other locations.”

Weathering processes are of three main types: mechanical, organic and chemical weathering.

A 2.0 m length of wire is made by welding the end of a 120 cm long silver wire to the end of an 80 cm long copper wire. Each pie
Levart [38]

<u>Explanation</u>:

Resistivity of silver wire =1.47 e-8 ohm meter

Resistivity of copper wire = 1.72 \mathrm{e}-8 \text { ohm meter }

Resistance = Resistivity *length/cross sectional area

R=\rho_{L / A}

So,

\begin{aligned}&I=A\left(V / P_{A g} L_{A g}+P_{C u} L C_{U}\right)\\&1=8104 \mathrm{A}\end{aligned}

For E calculation

For copper

E = resistivity * current density

E = Resistivity * current/area

E=4.9298 \mathrm{V} / \mathrm{m}

For silver

E=4.213 \mathrm{V} / \mathrm{m}

Potential difference $=E^{*} L$

For silver

Potential difference = 4.213^{*} 1.2=5.055 \mathrm{V}

For copper

Potential difference =3.9438 \mathrm{V}
