Answer: ECT

Explanation:

ECT is a process in which the patient is treated for the cases of several mental disorders, depression, loss of memory and confusion.

In this process an electric shock is induced to the brain when the anesthesia is given to the patient.The brain impulses are recorded and seen over a monitor screen.

A treatment in which an electrical current is applied to the brain is;

D. Electroconvulsive therapy

<u>An electric current would be transmitted through the brain without anesthesia through this method. However, there may be side effects of possible seizures or broken bones. </u>

A slingshot can project a pebble at a speed as high as 38.0 m/s. (a) If air resistance can be ignored, how high (in m) would a p

kipiarov [429]

Answer:

73.67 m

Explanation:

If projected straight up, we can work in 1 dimension, and we can use the following kinematic equations:

$y(t) = y_0 + V_0 * t + \frac{1}{2} a t^2$

$V(t) = V_0 + a * t$ ,

Where $y_0$ its our initial height, $V_0$ our initial speed, a the acceleration and t the time that has passed.

For our problem, the initial height its 0 meters, our initial speed its 38.0 m/s, the acceleration its the gravitational one ( g = 9.8 m/s^2), and the time its uknown.

We can plug this values in our equations, to obtain:

$y(t) = 38 \frac{m}{s} * t - \frac{1}{2} g t^2$

$V(t) = 38 \frac{m}{s} - g * t$

note that the acceleration point downwards, hence the minus sign.

Now, in the highest point, velocity must be zero, so, we can grab our second equation, and write:

$0 m = 38 \frac{m}{s} - g * t$

and obtain:

$t = 38 \frac{m}{s} / g$

$t = 38 \frac{m}{s} / 9.8 \frac{m}{s^2}$

$t = 3.9 s$

Plugin this time on our first equation we find:

$y = 38 \frac{m}{s} * 3.9 s - \frac{1}{2} 9.8 \frac{m}{s^2} (3.9 s)^2$

$y=73.67 m$

E asteroid belt circles the sun between the orbits of mars and jupiter. one asteroid has a period of 6.0 earth years. part a wha

anzhelika [568]

To solve the problem, use Kepler's 3rd law :

T² = 4π²r³ / GM

Solved for r :

r = [GMT² / 4π²]⅓

but first covert 6.00 years to seconds :

6.00years = 6.00years(365days/year)(24.0hours/day)(6...
= 1.89 x 10^8s

The radius of the orbit then is :

r = [(6.67 x 10^-11N∙m²/kg²)(1.99 x 10^30kg)(1.89 x 10^8s)² / 4π²]⅓
= 6.23 x 10^11m

If an object has a mass of 14 kg, what is it’s weight

Alex_Xolod [135]

Answer:

Weight = 137.2 kg.m/ $s^{2}$

Explanation:

Given

mass of an object, m = 14 kg

Weight (W) is given by the formula:

W = mg , where m is mass of the object and g is acceleration due to gravity and the value is 9.8 m/ $s^{2}$

Hence W = 14 kg x 9.8 m/ $s^{2}$

= 137.2 kg.m/ $s^{2}$

If you will be rinsing your regulator after removing it from the cylinder, you must make sure that the ______ ______ is firmly i

Rudik [331]

If you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.

A dust cap is a gently curved dome mounted either in concave or convex orientation over the central hole of most loudspeaker diaphragms.

Thus, if you will be rinsing your regulator after removing it from the cylinder, you must make sure that the dust cap is firmly in place.

EleoNora [17]

Answer:

c) paractically the same weight

Explanation:

The force of gravity acts on all apples on an apple tree. Some apples are twice as far from the ground as others. For the same mass these twice-as-high apples have _________.a) 1/4 weightb) 1/2 weightc) paractically the same weigh

from newton's law of motion

states that

the rate of change in momentum of a body is directly proportional to the force applied on the body

f $\alpha$ =mdv/dt

dv/dt=a

f=kma

f=ma, where k is constant and equal to 1

a=g since the body is falling under gravity

acceleration of the apples become acceleration due to gravity

W=mg

since they all have equal mass, then the weight on the body will be practically and obviously the same
