simple methods to carry a sufferer encompass the four-hand seat, backpack carry, ski pole or tree limb backpack carry, and coiled rope seat. In the first method, two rescuers interlock hands. Each rescuer first grasps his right wrist with his left hand.
The term that describes the direction closest to the point of origin is Proximal. Dorsal is the directional term for the movement toward the back of the body. Cephalic is the term that describes the movement towards the top of the body. Ventral on the other hand describes the movement toward the front of the body.
Answer:
the required distance is 6 cm
Explanation:
Given the data in the question;
f₁ = 15 cm
f₂ = 5.0 cm
d = 45 cm
Now, for first lens object distance s = ∝
1/f = 1/s + 1/s' ⇒ 1/5 = 1/∝ + 1/s'
Now, image distance of first lens s' = 15cm
object distance of second lens s₂ will be;
s₂ = 45 - 15 = 30 cm
so
1/f₂ = 1/s₂ + 1/s'₂
1/5 = 1/30 + 1/s'₂
1/s'₂ = 1/5 - 1/30
1/s'₂ = 1 / 6
s'₂ = 6 cm
Hence, the required distance is 6 cm
Answer: The net force is negative, The net force is positive, There is change in motion.
When an balanced force acts, there is change in motion. In case of balanced forces, the object does not change its motion. The unbalanced force causes change in the momentum of the object. There would be some net force. It would not be zero. The net force is zero when the acting forces are balanced. The net force in case of unbalanced forces have certain magnitude and are positive or negative depending on the direction. The positive and negative sign denotes direction of the net force.
<h3><u>Answer;</u></h3>
<em>Only some metals are attracted by magnets; these metals are called ferromagnetic.</em>
<h3><u>Explanation;</u></h3>
- <u><em>Magnets</em></u> are those materials that have the ability of producing magnetic field. Magnets attracts materials called magnetic materials and have no effect on non magnetic materials such as wood.
- <em><u>Magnetic materials </u></em>are materials that are attracted by a magnet, these includes some metal such as iron and steel. However some metals are non-magnetic materials, these include, gold, silver, and copper among others,
- Therefore, it would be appropriate to say that<em> </em><em><u>only some metals are attracted by magnets; these metals are called ferromagnetic.</u></em>
