First, find the amount of time for the dart to hit the board using this equation: t = d/v
t = 2 m/ 15 m/s = 0.133 s
Then, find the height the dart has fallen from its initial point using this equation: h = 0.5gt²
h = 0.5(9.81 m/s²)(0.133 s)² = 0.0872 m or 8.72 cm
Since the diameter of the bull's eye is only 5 cm, and you started at the same level of the top of the bull's eye, that means the maximum allowance would only be 5 cm. Since it exceeded to 8.72 cm, it means that <em>Veronica will not hit the bull's eye.</em>
1. Using Strong Permanent. 2. increasing the current. 3. Decreasing the space between Magnets
Explanation:
Brainiest
Answer:
The material with higher modulus will stretch less than
The material with lower modulus
Explanation:
A material with a higher modulus is stiffer and has better resistance to deformation. The modulus is defined as the force per unit area required to produce a deformation or in other words the ratio of stress to strain.
E= stress/stain
Hooks law states that provided the elastic limit is not exceeded the extension e of a spring is directly proportional to the load or force attached
F=ke
Where k is the constant which gives the measure of the spring under tension
Explanation:
Weak nuclear force:
The interaction between the subatomic particles is called weak nuclear force.
The weak nuclear force is one of the four fundamental forces.
The weak nuclear force is effective at very short distance.
The range and relative strength of weak nuclear force is 10⁻¹⁸ m and 10²⁵ with respect to gravitational force respectively
Deuterium is formed due to the fusion of protons and neutrons under the action the weak force.
Example : Beta decay
Electromagnetic force:
The interaction between the charged particles is called electromagnetic force.
The electromagnetic force is one of the four fundamental forces.
The electromagnetic force is effective at long range distance.
The range and relative strength of electromagnetic force is infinity and 10³⁶ with respect to gravitational force respectively
Example : light
