Determine the mechanical energy of this object a 1kg pendulum at a height of 1-meter

Lemur [1.5K]

Answer:

Step-by-step explanation:

Mechanical energy (ME) is Kinetic energy + potential energy

Where

Kinetic Energy (KE) = 1/2 * m * v^2

where m is the mass (in kg) and v is the speed of the object (in m/s)

and

Potential Energy (PE) = m*g*h

Where m is the mass (in kg) and g is the gravitational constant (9.81 m/s) and h is the height (in meters)

Hence

ME = KE + PE (note the pendulum DOES NOT have any speed, so v = 0, and thus KE = 0)

So,

$ME=KE+PE\\ME=\frac{1}{2}mv^2+mgh\\ME=\frac{1}{2}(1)(0)^{2}+(1)(9.81)(1)\\ME=0+9.81\\ME=9.81$

Hence, Mechanical Energy is 9.8 Joules (rounded to 1 decimal place). Correct answer is A.

What is the distance between points (5, 13)

horrorfan [7]

You are going to treat this as a triangle so one side is 13 units long and the other is 22. And using the pythagorean theorem a²+b²=c².

13²+22²=c²

169+484=c²

653=c²

√653=√c²

25.55386...=c

Or, rounded to the nearest hundredth, 25.55

Find the measure of ∠b.

luda_lava [24]

Answer:

B. 38°

Step-by-step explanation:

The angles of a triangle add up to 180.

So, 62 + 80 + b will add up to 180.

First, we add 62 =80, which gives us 142.

The we subtract 142 from 180, which gives us 38.

Help please and thank you

aksik [14]

Remember
$(a^b)^c=a^{bc}$
and
$\frac{x^a}{x^b}=x^{a-b}$

so

$\frac{(7^2)^5}{7^{-6}}=$
$\frac{7^{2*5}}{7^{-6}}=$
$\frac{7^{10}}{7^{-6}}=$
$7^{10-(-6)}=$
$7^{10+6}=$
$7^{16}$

the answer is D
