Answer:

b. 14.7%

Explanation:

Experimental value of gravitational acceleration “g” = 11.25 m/s^2

Actual value of gravitational acceleration “g” = 9.81 m/s^2

Percentage error = ((Experimental value – Actual value)/Actual value) × 100

Percentage error = ((11.25 – 9.81)/9.81) × 100                                          

Percentage error = 14.7%  

Hence, the percentage error in the value of “g” will be 14.7%.

What net force would be required for a 50.5 kg wolf to accelerate at 5.0 m/s^2
Basile [38]

Answer:

\boxed {\boxed {\sf 252.5 \ Newtons }}

Explanation:

Force is the push or pull on object that can cause different things, like acceleration. According to Newton's 2nd Law of Motion, it is the product of mass and acceleration.

F=m*a

The mass of the wolf is 50.5 kilograms and the acceleration is 5.0 meters per square second. Therefore:

  • m= 50.5 \ kg
  • a= 5.0 \ m/s^2

Substitute the values into the formula.

F= 50.5 \ kg * 5.0 \ m/s^2

Multiply.

F=252.5 \ kg*m/s^2

  • 1 kilogram meter per square second is equal to 1 Newton.
  • Our answer of 252.5 kg*m/s² is equal to 252.5 Newtons.

F= 252.5 \ N

The force required is <u>252.5 Newtons</u>.

Alternating current is normally produced by a
aliina [53]

Answer:

B) generator

Explanation:

Alternating current is a type of current that changes direction periodically which is produced by a generator. This generator consists of a magnet and a loop of wire which rotates in the magnetic field of the magnet.

Therefore, from the given question, alternating current is normally produced by a generator.

Option B is the correct answer

Introduction Team Problem 2 You jump into the deep end of Legion Pool and swim to the bottom with a pressure gauge. The gauge at
Kaylis [27]

Answer:

Depth of the pool, h = 4.004 cm

Explanation:

Pressure at the bottom, P = 39240 N/m²

The density of water, d = 1000 kg/m³

The pressure at the bottom is given by :

P = dgh

We need to find the depth of pool. Let h is the depth of the pool. So,

h=\dfrac{P}{dg}

h=\dfrac{39240\ N/m^2}{1000\ kg/m^3\times 9.8\ m/s^2}

h = 4.004 m

So, the pool is 4.004 meters pool. Hence, this is the required solution.
