Answer:
AC)=(AB)2+(BC)2−−−−−−−−−−−−√=42+32−−−−−−√
⇒displacement=16+9−−−−−√=25−−√=5m
Explanation:
the Moon passes between Earth and the Sun Even though the Moon is much smaller than the Sun, because it is just the right distance away from Earth, the Moon can fully block the Sun's light from Earth's perspective This completely blocks out the Sun's light

Can you do this questions?
Answer:
V1 = ____0.3______ m/s, V2 = ____-0.3______ m/s,
p1 = ____0.015______ kg m/s, p2 = ___-0.015_______ kg m/s,
ptotal = _0___________ kg m/s
Explanation:
Taking the marble ball that moves from right to left as Marble 1 and the one that moves from left to right as Marble 2. We take direction from left to right as negative and from right to left as positive. Therefore, velocity of marble 1 will be +0.3 m/s while velocity of marble 2 will be -0.3 m/s. The mass of marble 1, m2 0.05 Kg and same to marble 2, m2=0.05 Kg
Momentum is product of mass and velocity hence using p to represent momentum
P1=0.05*0.3=0.015 Kg m/s
P2=0.05*-0.3=-0.015 Kg m/s
V1=0.3 m/s, V2=-0.3 m/s
The total momentum before collision will be the sum of P1 and P2 hence 0.015 Kg m/s+-0.015 Kg m/s=0
Ptotal=0 Kg m/s
