Answer: The correct answer is Image B.
Explanation: For an object to accelerate, there should be unbalanced forces present. An object will move in the direction of net force.
Balanced forces are defined as the forces acting on the same object which are equal in magnitude but act in opposite direction. The net forces are 0.
Unbalanced forces are defined as the forces acting on the same object which are unequal in magnitude. The net force is non-zero.
For the given images:
Image A: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Image B: This box will not accelerate because the net force is zero as all the forces are balancing one another. Hence, the object will stay at rest.
Image C: This box will accelerate easily because the net force is non-zero and is acting in between the normal and applied force.
Image D: This box will accelerate easily because the net force is non-zero and is moving in right direction.
Hence, the correct option is Image B.
Fossil fuels like coal for instance , when they are provided with heat energy (heating them) they start producing Kinetic energy . This kinetic energy will be passed along a turbine which transforms this K.E to an electrical energy used in different useful forms.
Answer:
According to the parallelogram law of vector addition if two vectors act along two adjacent sides of a parallelogram(having magnitude equal to the length of the sides) both pointing away from the common vertex, then the resultant is represented by the diagonal of the parallelogram passing through the same common vertex

Answer:
Risk rejection
Explanation:
There are several factors that contribute to the degree of driving risks and they include but not limited to the ability of the driver and the condition of a vehicle. Other factors are condition of the environment and the condition of the highway. When driving, a driver may wait until an oncoming vehicle passes before making a complete left turn as a risk rejection strategy. Left turns are more dangerous when making them because drivers tend to accelerate on to a left turn. The wider radius of a left turn is know to led to higher speeds and greater pedestrian exposure. A driver is advised to have more mental and physical efforts when making a left turn.
It really doesn't matter whether the two masses are joined by a light string, a light reinforced concrete and steel frame, a light coating of strong glue, or a layer of scotch tape that's one atom thick. They look like a single mass of 10 kg.
<u>Part a). </u>Force = (mass) x (acceleration)
The acceleration of 10 kg of mass pulled with 100N of force is
100 N = (10 kg) x (acceleration)
Divide each side by (10 kg):
Acceleration = (100 N) / (10 kg)
<em>Acceleration = 10 m/s²</em>
<u>Part b).</u> Now look at just the rear 16 kg. It stays hooked onto the front 4 kg, and everything moves together. So both pieces must have the same distance, velocity, acceleration etc. We know that the acceleration is 10 m/s² .
Force = (mass) x (acceleration)
Force on the rear 16 kg = (16 kg) x (10 m/s²)
<em>Force = 160 Newtons</em>
