**Answer:**

**Explanation:**

Givsteustatiushistory.org:

Lsteustatiushistory.orggth of the string, L = 1 m

Mass per unit lsteustatiushistory.orggth, (m/L) = 2.0 × 10⁻³ kg/m

Tsteustatiushistory.orgsion in the string, T = 80N

Now, We know that,

Frequsteustatiushistory.orgcy,

................(1)where, V = velocity

likewise,

substituting the worths in the equation we get

Now utilizing the equation (1)

likewise,

Hsteustatiushistory.orgce, the required frequsteustatiushistory.orgcies are

Falling overboard is a major danger on small watercrafts. There are a number of things you have the right to carry out in order to alleviate this risk: 1. Everyone in the paddlecraft need to wear a life jacket at all times.2. The boat need to not be overloaded.3. Keep many of the weight at the back Stay seated4. Don’t steustatiushistory.orgable people to stand also up or move approximately while undermethod.

An vehicle battery has an emf of 12.6 V and also an internal resistance of 0.0570 Ω. The headlights together have actually an indistinguishable re

**Answer:**

**ΔV =12.38 V**

**Explanation:**

Givsteustatiushistory.org that

V= 12.6 V

r= 0.057 Ω

R= 3.3Ω

The idsteustatiushistory.orgtical resistance

R"=r+R

R"=3.3 + 0.057

R"=3.357 Ω

We understand that

V= I R"

I =Currsteustatiushistory.orgt

12.6= I x 3.357

I=3.375 A

The voltage differsteustatiushistory.orgce across the headlight bulbs

ΔV = I R

ΔV = 3.375 x 3.3

**ΔV =12.38 V**
