We can see that the range from the calculation is 310 m.
<h3>What is the range of a projectile?</h3>
When we throw something from a height and it lands at the same eight, we call it a projectile motion. A projectile must always be shot at an angle. The range of the projectile is obtained by the relation; R = u^2sin2θ/g
Thus;
g = acceleration due to gravity
θ = acute angle
u = velocity
R = (60)^2 sin2(30)/10
R = 310 m

Answer:
Induced emf,
Explanation:
It is given that,
Rate of change of magnetic field,
A UHF antenna is oriented at an angle of 47° to a magnetic field, θ = 47°
Diameter of the antenna, d = 13.4 cm
Radius, r = 6.7 m = 0.067 m
We need to find the induced emf of the antenna. It is given by :
Where
= magnetic flux,
So,
B = magnetic field
So, the induced emf of the antenna is 2.2 mV. Hence, this is the required solution.
Answer:
Refraction
Explanation:
Refraction, meaning passes through. Reflection is when light, heat, or sound bounces off a surface, kind of like an echo. Resonance is sound reverberating, or vibrating. And polarization is the action of not allowing the vibrations of a transverse wave. Hoped it help..
A) a piece of wire
Explanation:
Radhika's mother is simply replacing piece of wire.
A fuse is made up of a thin strip of wire that melts when there is an over current.
- A fuse is electrical safety device in circuit that protects appliances from over current.
- The wire in a fuse has a high resistance and low melting point.
- When current is high, the resistance of the wire causes it to melt and break the circuit.
- In this way, appliances are protected from the harmful effect of the surge in voltage.

Answer:
To show that magnets repel, you must place the strong and weak magnets to another magnet with their poles being both south or both north facing eachother.
To show they attract, place opposite poles near eachother.
