Answer:
Gamma rays
Explanation:
The penetrating power of gamma rays is maximum as compared to beta and alpha rays. Gamma rays are nothing but the photons i.e. the packets of energy. Their energy range lies from kilo electron volts to 8 mega electron volts. It is emitted during the decay of many radioactive isotopes, such as U-238 and I-131. A large amount of energy is produced in decay of uranium 238.
Hence, the correct option is " gamma rays ".
Answer:
32 meters
Explanation:
Given:
x₀ = 0 m
y₀ = 1 m
y = 1 m
v₀ₓ = 18 cos 52° m/s
v₀ᵧ = 18 sin 52° m/s
aₓ = 0 m/s²
aᵧ = -9.8 m/s²
Find: x
First, find the time it takes for the ball to be caught.
y = y₀ + v₀ᵧ t + ½ aᵧt²
1 = 1 + 18 sin 52° t + ½ (-9.8) t²
0 = 14.2 t − 4.9 t²
0 = t (14.2 − 4.9 t)
t = 0 or 2.89
It takes 2.89 seconds to be caught. The horizontal distance traveled in that time is:
x = x₀ + v₀ₓ t + ½ aₓt²
x = 0 + (18 cos 52°) (2.89) + ½ (0) (2.89)²
x = 32.1
Rounded to two significant figures, the ball travels 32 meters.
When cattle are processed, the most likely use for the animals' skin is in
the production of Leather.
<h3 /><h3>Animals used for Leather production</h3>
The commonly used animals in leather production is however cattle and
they amount for a large percentage of leather present today. They also
involve various techniques such as tanning and crusting to ensure
conversion to leather.
