Answer:

A) C is 2 units towards right

B) C is 9 units towards right and 3 units towards up

C) C is 4 units towards right and 1 unit towards down

Explanation:

Drawings are given in the attachment.

A)Since,

A is 4 units towards right,

B is 1 unit towards left,

Then,

C is 2 units towards right.

B) Since,

A is 4 units towards right and 2 units towards up,

B is 1 unit towards left,

Then,

C is 9 units towards right and 3 units towards up.

C) Since,

A is 4 units towards right and 2 units towards up,

B is 1 unit towards right, and 1 unit towards down

Then,

C is 4 units towards right and 1 unit towards down.

A element source has a decayed constant of 13.6pico per second. Calculate the half life of this element.

vladimir1956 [14]

Answer:

5.1 x 10¹⁰s

Explanation:

Given parameters:

Decay constant = 13.6 x 10⁻¹²/s

Unknown:

Half life of the element = ?

Solution:

From the decay constant, we can find the half-life of this radioactive element.

Half-life = $\frac{0.693}{decay constant}$

Half-life = $\frac{0.693}{13.6 x 10^{-12} }$ = 5.1 x 10¹⁰s

When two objects made of different materials are rubbed together, they will attract each other after the charging process.Immers

Sergio039 [100]

Answer:

True

Explanation:

because their is friction(e.g take a ruler rub it in your hair then put it on top of a piece of paper on the table then u will see the process)among the two objects.

It takes Harry 34 s to walk from x1 = -11 m to x2 = -54 m .

miss Akunina [59]

Missing question:
"What is his velocity? Please answer using two sig figs in m/s."

Solution
The relationship between velocity (v), space (S) and time (t) is
 $v= \frac{S}{t}$
The space covered by Harry is
 $S=x_1 - x_2 = -11 m-(-54 m)=43 m$
and so the velocity is
 $v= \frac{43 m}{34 s} =1.26 m/s$

Beam design what is the maximum code-allowable floor beam deflection under the given live load?

Irina18 [472]

According to I.S. standards, the maximum deflection should typically not be greater than 1/325 of the span.

<h3>What is Beam deflection?</h3>

A beam is a long segment of a body that can support a weight while defying bending. Beam deflection is the term for the movement of a beam when a force is applied to it in a certain direction.

The beam has the ability to be bent or shifted from its initial position. The deflection is represented by this distance along each member point.

The amount of displacement that a certain structural member may experience with the aid of a sizable amount of load is known as deflection. It may also be known as the angle or the separation. The slope of the deflected form of the body under a load directly influences the distance of deflection of a member under that force.

A horse 1 m tall running towards a tree at a constant velocity of 20m/s,

kykrilka [37]

The horse's position on the ground at time t is

x = (20 m/s) t

The baboon's height from the ground at time t is

y = 3 m - 1/2 g t²

where g = 9.80 m/s² is the magnitude of the acceleration due to gravity.

The baboon falls and lands on the horse, so that the two animals meet when the baboon's height is 2 m from the ground, which happens after

2 m = 3 m - 1/2 g t²

1/2 g t² = 1 m

t² = (2 m) / (9.80 m/s²)

t ≈ 0.452 s

In this time, the horse reaches the tree, so its distance from it is

(20 m/s) * (0.452 s) ≈ 9.04 m
