The tension has to hold the part of the weight in the direction of the string:

T = mg*cos(theta)

Theta=0, whole weight, theta=90, T=0, if the pendulum is horizontal, the string will be loose! Yeah

Answer:

So the tension  in the string T =mg cosθ

Explanation:

Now given that

mass of bob = m

Angle from vertical plane =θ

Lets T is the tension in the string

From the diagram

Weight of bob have two component ,first one(mg cosθ) balance the tension in the string and other one(mg sinθ)  make the bob to move in the plane.

So the tension  in the string T =mg cosθ

Consider a horizontal, uniform board of weight 125 N and length 4 m that is supported by vertical chains at each end. A person w
Norma-Jean [14]

Answer:

b. 375 N

Explanation:

System of forces in balance

ΣFy = 0 Equation (1)

Forces acting on the board

T₁: Tension in the  left chain ,  vertical and upward

T₂ = 250 N : Tension in the right chain ,  vertical and upward

W₁ = 125 N : Weight of the  board , vertical and downward

W₂ =  500 N : Weight of the  person , vertical and downward

Calculation of the T₁

We apply the Equation (1)

ΣFy = 0  

T₁+T₂-W₁-W₂ = 0

T₁ = -T₂+W₁+W₂

T₁ = -250 N+ 125 N+ 500 N

T₁ = 375 N

Answer:

D) The given reaction is Exothermic, because energy is released

Explanation:

Here, given that Zinc is added to a beaker containing hydrochloric acid.

Also, the beaker gets warm.

⇒The energy is released in the form of heat.

EXOTHERMIC reactions are those type of reactions in which energy is released in the form of heat.

When the beaker gets warm, the reaction is exothermic in nature.

Hence, the given reaction is Exothermic, because energy is released

How is acceleration related to force when mass is constant, according to Newton's second law of motion?
kherson [118]

Answer:

According to Newton's second law of motion, acceleration is directly proportional to force. As the force increases (when mass is constant), the acceleration increases. This can be shown in the following formula.

f = ma

a =  \frac{f}{m}

f = force

m = mass

a = acceleration
