The elastic modulus is solely reliant on the material type, which varies among different materials based on their physical characteristics. It does not rely on the wire's length, cross-sectional area, or the force applied to the wire. Therefore, wire length does not influence the elastic modulus. As both wires are crafted from the same metal, their elastic moduli will be identical.

Yuliya22 [2438]

Answer:

50.2 cm

Explanation:

We have the following data:

Height, h=3.5 m

Initial horizontal velocity, u_x=15 m/s

Time, t=0.32 s

We need to determine how far the ball is from the ground after 0.32 s.

Initial vertical velocity, u_y=0

s=u_yt+\frac{1}{2}gt^2

Where g=9.8 m/s^

s=0+\frac{1}{2}(9.8)(0.32)^2

s=0.502 m

s=0.502\times 100=50.2 cm

Keith_Richards [2263]
The first word in the blank is "pours out of you," while the second word to fill in is "diffuse." This implies that a person with an effusive nature tends to openly express their feelings, just as spilled motor oil will spread out over gravel.

Three identical filing cabinets have two drawers each. There are also three equal stacks of paper. Cabinet A: In the first filin
ValentinkaMS [2425]

Response:

Ranking from highest to lowest: B, A, C

Explanation:

Each is affected equally by the total force (the weight of the paper stacks). A body that maintains rotational stability will likely roll under torque or a moment around an axis.

The moment for these cabinets relevant to their axis amplifies with increased perpendicular distance, which grows as they open more.

The gravity tractor is a proposed spacecraft that will fly close to an asteroid whose trajectory threatens to impact the Earth.
serg [2593]
First, determine the asteroid's mass by calculating its volume and using the density of iron. If r = d/2 = 645 ft, then: Once you have both masses, apply Newton's law of gravitation to find the force of attraction: Where G is the gravitational constant.

Starting from rest, the boy runs outward in the radial direction from the center of the platform with a constant acceleration of
Softa [2035]
The velocity when t=3 seconds is V=1.56 m/s. Given that acceleration a=0.5 m/s², angular velocity ω=0.2 rad/s, and time t=3 seconds, we calculate radial velocity Vr as Vr = a*t, leading to Vr = 1.5 m/s. The radius r is then calculated as r = a*t²/2, yielding r = 2.25m. The tangential velocity Vt is Vt = ω*r, resulting in Vt = 0.45 m/s. Finally, the total velocity V is computed as V = √(Vr² + Vt²), giving V = 1.56 m/s.
