What would be the force required to accelerate an object that weighs 35 N up at a rate of .60 m/s^2?

Physics

Answer: 2.14\ N

Explanation:

Given

Force required to accelerate the object at the rate of 0.6\ m/s^2

The weight of the object is W=35\ N

Mass of the object can be identified by dividing the weight by acceleration due to gravity

\Rightarrow m=\dfrac{W}{g}\\\\\Rightarrow m=\dfrac{35}{9.8}\\\\\Rightarrow m=3.57\ kg

\therefore \text{Force F=}m\times a\\\Rightarrow F=3.57\times 0.6\\\Rightarrow F=2.14\ N

Due to an influx of wild animals, you need to enclose your garden. You have 500 feet of fencing and will enclose the garden on t
elena55 [62]

Answer:

so  length of the fence  is 250 feet

Explanation:

Given data

fencing (L) = 500 feet

enclose the garden = 3 sides

to find out

length of the fence

solution

we consider barn length x and width y

so we say  x +2y = 500   ........1

we want to maximize length i.e xy = f

so we say

df/dx = ƛ × dL/dx

y =  ƛ × 1

and

df/dy = ƛ × df/dy

x = ƛ × 2

from equation 1 we can say

2 ƛ + 2 ƛ = 500

so  ƛ = 500/4 = 125

so that x = 2× 125 ,  y = 125

so x = 250 , y = 125

so  length of the fence  is 250 feet

Need help in Psychology. Please help! Which of the following statements best describes abductive reasoning? A.I think,therefore
Pepsi [2]
The "D) People perceive objects as a whole" statement best describes an abductive reasoning. The abductive reasoning often has incomplete information as the base of its reasoning and the conclusion for this type of reasoning is not absolute. There will always be additional pieces of evidence and factors that could change the conclusion of this reasoning. Therefore<span> D statement is the most suitable answer.</span>

Answer:

p = mv

Explanation:

  • The momentum of a body is defined as the product of its mass and velocity. Its physical symbol is 'p'.
  • The formula for momentum is given by

                               p = mv

         Where,

                                m -  the mass of the body in kg

                                v - velocity of the body in m/s

  • Therefore, the unit of momentum is expressed as the kg m/s
  • The momentum of a body is always associated with its motion. It is a vector quantity and it is directed in the direction of the velocity vector.
  • If a body is at rest, the momentum associated with the body is zero.
  • The momentum plays a significant role in the kinematics of the body. As similar to the energy conservation law, the total momentum of the body is conserved.

If a mass of 76 kg acts downward 0.38 m from the axis of rotation on one end of a board and another force of 129 N also acts dow
Semenov [28]

Answer:

y = 2.196 m

Explanation:

Mass, m = 76 kg

distance from axis of rotation, x = 0.38 m

Second Force, F = 129 N

moment arm of the second force, y = ?

Now, equating moments for the equilibrium

So,

m g × x = F x y

76 x 0.38 x 9.81 = 129 x y

y = \dfrac{76\times 0.38\times 9.81}{129}

y = 2.196 m

Hence, the length of the moment arm is equal to 2.196 m.
