Answer:
<h3>4.0Wb/m²</h3>
Explanation:
Magnetic flux Ф is expressed using the formula;
Ф = BA
B is magnetic field
A is the area of the square conductor
Given
B = 1.0T
A =L²
Area A = 2.0² = 4.0m²
Get the magnetic flux
Ф = 1.0 * 4.0m²
Ф = 4.0Wb/m²
Hence the magnetic flux through the conductor is 4.0Wb/m²
Answer:
W= 1812.6 J
Explanation:
Work (W) is defined as the scalar product of force F by the distance (d) the body travels due to this force.
W= F*d* cosα Formula ( 1)
Where:
F is the force in Newtons (N)
d is the displacemente in meters (m)
α : Angle formed between force and displacement
Data
F = 10 N
d = 200 m
α = 25°
Work done by the pulling force while the passenger walks 200 m
We replace data in the formula (1)
W= F*d* cosα
W= (10 N)*(200 m)* cos25°
W= 1812.6 (N*m)
W= 1812.6 J
Answer:
An unbalanced force can change an object's motion. An unbalanced force acting on a still object could make the object start moving. An unbalanced force acting on a moving object could make the object change direction, change speed, or stop moving.
Answer:
Your answer will be C. 3.8 kPa.
We will apply:
Q = mcΔT; where Q is the heat, m is the mass, c is the specific heat capacity and ΔT is the temperature change.
30,000 = 390 x 3.9 x ΔT
ΔT = 19.7 °C
The temperature change is of 19.7 °C.
